Hi CS! I've never made quiche without cheese, but I think it would work. LOL Here are two of my favorite quiche recipes; one with a crust and one without. All you really would have to do is put the cooked ground beef, spinach, and whatever else you want, like onions and spices, on the crust then pour the egg/milk mixture over it all and bake until the eggs are set....or for the crustless, just mix it all together and bake it.
Quiche
1 refrigerated pie crust, 9 inch
1 pound bacon or sausage, cooked and crumbled or 1 cup diced ham
1/3 cup onions, finely chopped
1 cup cheddar or Swiss cheese, shredded
1 cup grated Parmesan cheese
4 eggs, beaten
1 1/2 cups milk or heavy cream
Salt and pepper, to taste
Place crust in 9 inch glass pie pan. Layer meat, onions, peppers then cheeses in pan. Combine eggs, milk, salt, and pepper, then pour over layers. Bake at 375 degrees for 40 to 45 minutes until the eggs are set and top is light brown.
Crustless Quiche
You can vary this recipe to suit your tastes. It is great with cooked bacon, cooked sausage, steamed broccoli, mushrooms, artichokes. I also like swiss, gruyere and mozzarella cheese or a combination. Just depends on what I have on hand.
2 cups milk
4 eggs
3/4 cup biscuit baking mix
1/4 cup butter, softened
1/3 cup onions, finely chopped
1 cup grated Parmesan cheese
1 (10 ounce) package chopped frozen spinach, thawed and drained
1 cup cubed cooked ham
8 ounces shredded Cheddar cheese
Preheat oven to 375 degrees. Lightly grease a 10 inch quiche dish.
Beat together milk, eggs, baking mix, butter, onions and Parmesan cheese. Stir in spinach, ham and Cheddar cheese. Pour into dish and bake for 50 minutes, until eggs are set and top is golden brown.
Edited to add: Well, CS, as I hit Post, I saw where you mentioned pasta in the heading. LOL Now I don't have a clue!
