Heat panini grill to medium-high heat, (or large skillet). Spray with cooking spray.
Place wrap (one at a time) on panini grill/skillet and sprinkle 2 tbs parmesean cheese across one side of wrap. Add 1 serving of ham, half of onion and tomato on top of cheese. Spread about 1 tbs hummus on the other side of the wrap, then fold in half.
Close panini press, (or if using a skillet, heat one side at a time, flipping when each side is golden brown, about 1-2 minutes).
Serve with the rest of the red pepper hummus for dipping!
*You could aslo add cooked veggies, chicken, or turkey to make your own version of this quesadilla!
