This is a nice easy lunch dish or a dinner-for-one for those days when you don't have a lot of time to spend in the kitchen and don't want to sacrifice your good taste. The cheeses bring out the creamy zip of the dressing, and the veggies are a super satisfying compliment. You can try other vegetables to substitute, but be careful not to cut them to large or pile them on too thick. This pizza is great with a nice tossed salad on the side and a tall glass of iced tea.
Preheat broiler, preferably in a toaster oven. Prepare a small pan with cooking spray.
Spread dressing on surface of pita, leaving about a quarter inch from the edges. Sprinkle on mozzarella and cheddar.
Arrange zucchini over cheese layer, sprinkle with cheese, and then evenly distribute pepper rings over top. Do not make toppings too thick, or they won't cook. Sprinkle with feta. Broil pizza for 2-3 minutes or until feta is lightly browned and veggies are a little soft. ** If you like your peppers much softer, you can pre-broil them whole, let them steam in a paper bag for ten minutes, and then peel the skins before slicing.
