Polish Noodle Casserole

Ingredients

5/8 c sour cream
5/8 c cottage cheese
2 tb onion
2 tb salt
1/2 ts powdered mustard
1/4 ts pepper
1 quart casserole dish

Instructions

To be a bit more fancy, when the 25 minutes is over, pull the casserole out of the oven, smear it with a bit of butter, and allow it to cook another 5 to 10 minutes. To be even more fancy, sprinkle some parmesan cheese on top of the butter before putting the casserole back into the oven.
