It’s ridiculously easy!
Mix together 3 tbsp flour and 1/2 stick melted butter or margarine. Stir in 1/2 package of frozen chopped spinach, thawed. Do not drain. Add three eggs, one 12-ounce container of small curd cottage cheese and 6 ounces of grated cheddar cheese. Bake in unbuttered 8-inch pie plate for at least 35 minutes or as long as necessary.
I usually add a chopped shallot and pinch of pepper and nutmeg. Also, on the cheddar cheese, use a combination of other cheeses with it: Gruyere, Ridder, Swiss, etc. to vary the flavor somewhat.
