Begin by preparing your fresh ingredients for the Mediterranean Veggie Sandwich. Thinly slice one Roma tomato, a mini cucumber, and the red onion, aiming for uniform pieces for easy layering. If using jarred roasted red peppers, slice them into strips. Set all the vegetables aside on a cutting board.

Take a slice of whole wheat bread and generously spread hummus over one side, ensuring an even layer covers the entire surface. For added flavor, you can sprinkle tofu feta on top of the hummus if desired.

Layer the thin slices of red onion on top of the hummus, followed by the roasted red pepper strips, cucumber slices, and tomato. Finish with a handful of arugula.

Carefully place the second slice of whole wheat bread on top. Gently press down and cut the sandwich in half diagonally before serving.
