Prepare and cut the vegetables. Combine in a mixing bowl all of the above ingredients, except the tomatoes, basil leaves, dressing, and pita halves. You may leave the chickpeas out, if you wish.
Toss vegetable mixture to lightly glaze the vegetables with olive oil.
Spoon vegetable mixture onto a broiler pan or cookie sheet coated with nonstick cooking spray. Broil 5 minutes, add tomatoes and basil leaves to vegetable mixture and stir. Baste with additional marinade and broil for an additional 5 minutes or until vegetables are just tender and lightly browned. Tomatoes and basil should be just warmed; if you prefer the tomato softer, add with vegetable mixture at the beginning.
Prepare the dressing while vegetables are broiling.
Divide the vegetable mixture evenly between pita halves. Drizzle with Creamy Feta Dressing. Serve.
Creamy Feta Dressing:.
Combine all ingredients except the dill into a blender and blend until smooth.
Scrape the sides of the blender as needed. Add more milk as needed to get a consistency that is rather thin and pourable.
Pour into a bowl and sir in dill. Add more lemon juice if a tangier taste is preferred. Enjoy! This makes enough for 2-4 servings.
