Everything-but-the-kitchen-sink quiche

I dont usually add a crust to my quiche, since I dont really like making crust. Just make sure to grease your pans before pouring in the filling and it will form its own crust.

1/2 small onion, chopped
2 Tbsp butter
2 handfuls fresh spinach
1 can ham, crumbled
1/2 c. milk
1/4 c. flour
1 can white beans, drained and pureed
1 c. cheddar cheese, grated
3/4 c. mozzarella cheese, grated
2 oz. fresh grated Parmesan cheese
2 oz. asiago cheese
Salt & pepper to taste

2 crusts

Saute onion in butter until translucent. Add spinach and cook until dark and wilted. Add ham and remove from heat. In a blender combine milk, flour, and white beans. Blend until smooth. Add salt and pepper to taste. Add milk mixture from blender to the spinach. Stir in cheese.

Pour into crusts and cook at 350 until puffed and golden and the egg is completely set.

Remove from oven and let stand 10 minutes before cutting
