How to Make Marinated Tomato Sandwich with Cashew Tofu Spread and Sumac Onions Recipe

Step 1: Prepare the Cashew Tofu Spread

Start by soaking the raw cashews in boiling water for about 15 minutes to soften them, which is key for achieving that irresistibly smooth texture. Drain the soaking water, then combine the cashews with drained extra firm tofu, garlic, nutritional yeast, lemon juice, apple cider vinegar, white miso paste, salt, and olive oil in a blender. Blend on high until the spread is completely smooth, stopping to scrape down the sides if needed. Pop the mixture in the fridge to set – overnight if you can wait for a firmer consistency. This spread is the creamy, tangy heart of your sandwich.

Step 2: Marinate the Sumac Onions

While the spread chills, toss thinly sliced red onions with extra virgin olive oil, red wine vinegar, lemon zest and juice, sumac, a pinch of kosher salt, and minced parsley in a bowl. Use a spoon or clean hands to mix everything well, then let the onions sit for 10 to 15 minutes. This quick marination softens the onions and infuses them with that signature tangy twist that will make every bite sparkle.

Step 3: Marinate the Tomatoes

In another shallow bowl, combine extra virgin olive oil, garlic, parsley, basil, lemon zest, and lemon juice. Add heirloom tomato slices, coating each piece thoroughly in the flavorful marinade. Sprinkle lightly with salt, then let the tomatoes sit for 5 to 10 minutes. This step is magic for drawing out the tomatoes’ natural sweetness and layering in fresh herbal goodness.

Step 4: Assemble the Sandwich

Toast your favorite whole grain or sourdough bread slices. On one slice, layer optional avocado slices for extra creaminess, then spread a generous amount of your chilled cashew tofu spread evenly. Add the marinated tomato slices, followed by a heap of sumac onions and a few lettuce leaves if you like that fresh crunch. Drizzle any leftover tomato marinade over the lettuce for an extra flavor kick. Spread some more tofu mixture on a second bread slice, then top off your sandwich and give it a gentle press. This is where all those delicious layers come together perfectly.

Garnishes

Fresh herbs like additional minced parsley or basil sprinkled on top can add that extra burst of color and flavor right before serving. A light drizzle of extra virgin olive oil or a pinch of flaky sea salt brings a final flourish that elevates your sandwich to something truly special.

Side Dishes

Keep it light and complementary with simple side salads, perhaps a crisp arugula with lemon vinaigrette, or pair with roasted sweet potato wedges for a satisfying crunch that contrasts beautifully with the sandwich’s creamy textures. Fresh fruit or pickled vegetables also make fantastic companions, balancing richness with their bright and tangy profiles.

Creative Ways to Present

For a picnic or party, slice the sandwich into smaller finger portions and secure with decorative toothpicks. Serve with colorful napkins and your favorite chips or crudites to make a delightful spread. You can also turn it into a wrap using large lettuce leaves as a gluten-free option, or create an open-faced version on toasted bread to showcase those gorgeous marinated tomatoes and onions.

Make Ahead and Storage

Storing Leftovers

You can store any leftover cashew tofu spread in an airtight container in the fridge for up to 4 days, keeping it wholesome and ready for a quick snack. The marinated tomatoes and sumac onions keep well together in the fridge for about 2 days, though the bread is best served fresh to maintain that perfect texture and flavor balance.

Freezing

The tofu spread freezes well for up to 3 months if you want to prepare in bulk. Simply portion and freeze in airtight containers or freezer bags. When ready to enjoy, thaw overnight in the fridge and stir well to restore its creamy consistency. Avoid freezing the tomatoes and onions as their texture will change noticeably upon thawing.

Reheating

This sandwich is best enjoyed cold or at room temperature to preserve the freshness of the ingredients. If you prefer warmed bread, toast your slices just before assembling the sandwich, then add the chilled spread and marinated vegetables. Avoid microwaving the assembled sandwich to keep those fresh flavors and textures intact.

FAQs

Can I use other types of tofu?

Extra firm tofu works best because it holds its shape and blends smoothly, but if you only have firm tofu, that can work too. Just press it well to remove excess moisture before blending for the best texture.

What if I don’t have sumac?

You can substitute sumac with a squeeze of fresh lemon juice or a sprinkle of lemon zest combined with a pinch of smoked paprika for a slightly different but still flavorful twist.

Can I make this recipe vegan?

Yes, the entire Marinated Tomato Sandwich with Cashew Tofu Spread and Sumac Onions Recipe is plant-based and vegan-friendly, making it a perfect option for those following a vegan lifestyle.

Is there a gluten-free bread option?

Absolutely! You can use your favorite gluten-free bread to make this sandwich without missing a beat on taste or texture.

How long do I need to marinate the tomatoes and onions?

The tomatoes benefit from about 5 to 10 minutes of marinating, while the sumac onions take a bit longer, around 10 to 15 minutes to soften and develop their tangy flavor. This short marination time keeps things quick yet flavorful.
