Step‑by‑Step Instructions for Marinated Tomato Sandwich
Step 1: Soak Cashews
Begin by soaking the cashews in boiling water for about 15 minutes to soften them, which will help create a creamy texture for your dairy-free spread. Once the time is up, drain the cashews and combine them with extra firm tofu, fresh lemon juice, and zest in a blender. Blend until smooth and creamy, then chill in the fridge for a little while to firm up.
Step 2: Prepare Sumac Onions
While your tofu spread chills, slice the red onions and combine them in a bowl with olive oil, vinegar, lemon juice, sumac, salt, and freshly chopped parsley. Allow the mixture to sit for 10 to 15 minutes at room temperature. This marinating process will soften the onions and enhance their flavor, making them a zesty topping for your marinated tomato sandwich.
Step 3: Marinate Tomatoes
Next, slice your ripe heirloom or hothouse tomatoes to showcase their juicy goodness. In a separate bowl, whisk together olive oil, minced garlic, and chopped herbs like parsley and basil. Coat the tomato slices with this mixture and let them sit for 5 to 10 minutes. The marinated tomatoes will soak up the flavors and become the star of your sandwich.
Step 4: Assemble the Sandwich
Now that all your components are ready, it’s time to assemble your delicious marinated tomato sandwich. Start by spreading a generous layer of the chilled tofu mixture on one slice of hearty bread. Add a few slices of marinated tomatoes, a scoop of the sumac onions, and a handful of crisp lettuce for that refreshing crunch.
Step 5: Add Final Touches
For an extra layer of indulgence, consider adding slices of avocado for creaminess. Top with another slice of bread if you prefer a fully stacked sandwich, or serve it open-faced for a beautiful presentation. Enjoy your vibrant marinated tomato sandwich immediately, or store any leftovers in the fridge for a delightful, quick meal later!
