Mom'S Spinach Quiche - cooking recipe

Ingredients

1 (10 ounce) package frozen chopped spinach (or 2 cups cooked fresh spinach)
2 cups nonfat cottage cheese (or ricotta cheese)
3 large eggs
1/4 cup whole wheat flour (or any type of flour will work, gluten-free brown rice flour works well)
1 cup shredded part-skim mozzarella cheese (or any cheese will do)
salt and pepper
feta cheese (optional topping)

Preparation

Preheat oven to 350 degrees.
Thaw spinach in the microwave. (Substitute - cook fresh spinach in skillet with a small amount of olive oil to make 2 heaping cups cooked).
In a large bowl mix together cottage cheese (substitute ricotta if desired), eggs and flour. Then mix in the thawed spinach and shredded cheese and add salt and pepper to taste (about 4 shakes of salt and a couple shakes of pepper).
Scoop mixture into 9\" pie plate with our without pie crust and spread around evenly with a spatula.
No Crust: Bake for 45-60 mins or until fork in the center comes out clean and it is slightly browned around the edges (depending on the depth of the pan, cooking time will vary).
Crust: Bake for 1-1.25 hours. I do an 8\" pie pan for 1 hour and 15 minutes. I recommend covering the edges of your crust with foil until the last 15 mins or so of baking (the thicker the crust, the less it will brown).
Serve warm topped with crumbled feta cheese if desired.
