My grandmother's recipe. If you want to reduce the calories I would recommend half the cheese and a low-fat sour cream.
- Preheat oven to 350 degrees Fahrenheit.
- Mix ingredients together in a large bowl.
- Pour into a 9 x 13 inch dish.
- Bake at 350 degrees for one hour.
- Top with crushed potato chips for the last 5 minutes of the hour.
