For the Tofu Spread
- Tofu – Extra firm is best; press softer tofu for 15 minutes for a creamier texture.

- Lemon – Fresh juice and zest brighten up the spread—opt for juicy lemons for the best flavor.
For the Marinated Tomatoes

Step‑by‑Step Instructions for Marinated Tomato Sandwich
Step 1: Prepare the Tofu Spread
Begin by soaking the cashews in boiling water for about 15 minutes to soften them. Drain the cashews, then combine them with the extra firm tofu, lemon juice, and zest in a blender. Blend until the mixture is incredibly smooth and creamy. Transfer it to a bowl and refrigerate for at least 30 minutes to allow it to firm up while flavors meld, creating a delicious spread for your marinated tomato sandwich.
Step 2: Marinate the Onions
While the tofu mixture chills, finely slice the red onions and place them in a bowl. Drizzle with olive oil, vinegar, lemon juice, sumac, and a pinch of salt. Toss well so each onion slice is coated in the marinade. Let the onions marinate for 10-15 minutes, stirring occasionally until they soften and absorb the vibrant flavors, setting the stage for your marinated tomato sandwich.
Step 3: Marinate the Tomatoes
Next, slice the heirloom tomatoes into thick rounds and place them in a shallow bowl. Drizzle the remaining marinade ingredients over the tomato slices, ensuring they are well coated. Allow them to sit for 5-10 minutes, turning occasionally to enhance their flavor. This step enriches the tomatoes with a tangy kick that perfectly complements the creamy tofu spread in your marinated tomato sandwich.
Step 4: Assemble the Sandwich
It’s time to bring your marinated tomato sandwich together! Start with a slice of hearty bread and spread a generous layer of the tofu mixture on one side. Next, layer on the marinated tomato slices followed by the sumac onions and a handful of fresh lettuce for crunch. Top with another slice of bread, also spread with tofu mixture, and press gently to combine all those wonderful flavors.
Step 5: Serve and Enjoy
Slice the assembled marinated tomato sandwich in half and serve immediately for the freshest taste. Feel free to pair it with crispy chips or a light salad to round out your meal. The vibrant colors and flavors will not only satisfy your hunger but also provide a refreshing plant-based delight that’s perfect for any occasion.

Storage Tips for Marinated Tomato Sandwich
Fridge: Store prepared marinated tomatoes and sumac onions separately in airtight containers for up to 3 days to maintain freshness.
Tofu Spread: Keep the tofu spread in the fridge for up to 7 days. It can also serve as a delicious dip or spread for other dishes.
Assembling: For the best taste, assemble your marinated tomato sandwich just before serving. If you need to make it in advance, layer the ingredients without marinating the tomatoes until you’re ready.
Freezer: Although freezing is not recommended as it may affect the texture of the tomatoes, you can freeze the tofu spread for up to 3 months. Thaw in the fridge before use.
Expert Tips for the Best Marinated Tomato Sandwich

Marinate with Care: For a milder onion flavor, soak red onions in cold water for 10 minutes before marinating. This simple trick enhances the taste of your marinated tomato sandwich.
-
Choose the Right Bread: A hearty bread like sourdough or sprouted whole wheat adds structure to your sandwich. Avoid soft bread, which can get soggy from the marinated ingredients.

Fresh Ingredients Matter: Use fresh, locally sourced tomatoes for optimal flavor. Look for heirloom varieties that are ripe and slightly soft to the touch.
