Um, when I first glanced at the title of this thread, I thought it said "quickies." Of course, I had to open it up immediately.
And now you've all made me hungry. Here's a good crustless quiche recipe. Note that you can use any variation of cheese/vegetable as others have mentioned, but this is the recipe as I originally found it. FYI, I have no idea how long it lasts, since every time I've made it, people eat it all. I've only ever tried a slice once!
1 tablespoon vegetable oil
1 onion, chopped
1 (10 ounce) package frozen chopped spinach, thawed and drained
5 eggs, beaten
3 cups shredded Muenster (or other) cheese
1/4 teaspoon salt
1/8 teaspoon ground black pepper
Preheat oven to 350 degrees. Lightly grease a 9 inch pie pan.
Heat oil in a large skillet over medium-high heat. Add onions and cook, stirring occasionally, until onions are soft. Stir in spinach and continue cooking until excess moisture has evaporated.
In a large bowl, combine eggs, cheese, salt and pepper. Add spinach mixture and stir to blend. Scoop into prepared pie pan.
Bake in preheated oven until eggs have set, about 30 minutes. Let cool for 10 minutes before serving.
Variation: Instead of one large quiche, pour the mixture into the bottoms of a greased muffin pan, a little less than half full. It makes bite sized portions that are perfect for a party.
