Begin by washing and drying all vegetables: the Roma tomato, mini cucumber, red onion, and roasted red pepper. Slice the tomato and cucumber into evenly spaced rounds about 1/4 inch thick, and do the same for the roasted red pepper. For the red onion, slice it thinly to maximize its sharp flavor.

Take two slices of whole wheat bread and place them on a clean cutting board. Generously spread hummus over one side of each slice, ensuring the layer is even for a creamy texture. If you're using tofu feta, crumble it on top of the hummus on one slice.

On the hummus-covered slice, start layering your sliced veggies. Begin with a layer of red onion, followed by the roasted red pepper, cucumber, and finally, the Roma tomato slices. Top it off with a handful of fresh arugula.

Gently place the second slice of bread, hummus side down, on top of the veggie layers. Press down lightly but firmly to help bind the sandwich together.

Using a sharp knife, cut the sandwich diagonally from corner to corner. Serve your Mediterranean Veggie Sandwich immediately.
