But! This worked well, and was delicious, and was quick, so I had to share!
Spinach-Swiss Crustless Quiche
1 onion, chopped
2 garlic cloves, chopped
10 oz frozen chopped spinach, thawed
salt and pepper
6 slices Swiss cheese
Preheat oven to 350 F. Sauté onion and garlic in olive oil. Squeeze spinach dry and add to skillet. Cook 5 minutes or so; remove from heat. Crack eggs into a mixing bowl and whisk thoroughly, adding salt and pepper to taste. Slowly add in vegetables, stirring constantly to keep the heat from cooking the eggs. Pour half of egg mixture into a greased pie plate. Top with the slices of Swiss, and pour the rest of the egg mixture on top of that. Bake for 20-30 minutes. (Our oven doesn't hold heat well, so it took 30; I'd start checking it at 15 or 20 minutes.)
