I love Pampered Chef's version of this recipe but I don't want to turn the oven on during hot weather. Using a Boboli crust and vegetables from the grocery store salad bar make this recipe ultra easy and simple. I don't recommend using tomatoes or mushrooms in this recipe unless it will be eaten in one day. The tomatoes and mushrooms will get mushy if any is leftover. Peppers, carrots, red cabbage, broccoli, cauliflower provide great crunch and color. Enjoy!
