Here's the recipe (don't forget, I doubled the recipe to get a full 9x13 pan's worth):
Heat the oven to 400 degrees. Spray a square baking dish (8x8x2) or a pie plate.
1 cup chopped zucchini
1 cup chopped tomato
1/2 cup chopped onion
1/2 cup grated Parmesan cheese
-I also added fresh broccoli because we had it in the fridge. I chopped it up pretty small. You could also add potatoes! If you want to add cooked meat like ham, bacon, or sausage you'll probably want to omit the salt and reduce the pepper (which follows).
Sprinkle above ingredients evenly in pan.
In a separate bowl blend 1 minute or until smooth:
1 cup milk
1/2 cup Bisquick baking mix
2 eggs
1/2 t. salt
1/2 t. pepper
Then pour batter evenly over veggies and cheese. Bake 30-35 mins.* or until knife inserted in center comes out clean. Let stand 5 minutes before cutting. Serves 6.
*For the double portion, I added an extra 15 minutes to the cooking time and it came out perfectly. As you can tell, John and I took out 6 portions on our own!! We were hungry!
