Preheat oven to 350
Mix together in a large bowl: (liquid first)
4 eggs slightly beaten
1/2 cup canola or vegetable oil
2 teaspoons garlic salt
2 teaspoons oregano (or basil, parsley, rosemary, thyme)
1/2 cup chopped onions
1 cup grated cheese (i used cheddar, but you can use other kinds)
1 cup Bisquick
3 cups thinly sliced zucchini
Pour evenly into a 9X13 greased pan (i use nonstick spray)
Cook for 30-35 minutes at 350. Then cook on low broil for 5-10 minutes depending on how brown you want it on top.
