Chad and I were invited to a friends house for the 4th. I needed to bring a dish but I didn't want to bring something predictable like potato salad or baked beans (I was sure that would already be there). I came across this recipe and it looked super simple and delicious.
Bake at 375° for 6 minutes or until lightly browned. Gently press crust down with a wooden spoon. Spread crust with mustard, and set aside.
Heat a large skillet over medium heat and add 3 Tbs. olive oil and butter spray. Put onions in skillet and saute a couple minutes. Add zucchini, squash and prosciutto and saute about 5 More minutes. Add garlic and saute about a minute more. Remove from heat; stir in parsley and next 5 ingredients.
Whisk together eggs and milk in a large bowl; stir in cheese and vegetable mixture. Pour over crust.
Bake at 375° for 20 to 25 minutes or until a knife inserted in center comes out clean. Garnish, if desired.
*1 1/2 pounds zucchini may be substituted for yellow squash.
