I got this recipe from a coupon booklet from Proctor & Gamble. It looked pretty easy & yummy.
1 can cream of mushroom soup
2 cups milk
1 cup shredded cheddar cheese
1 1/2 cups finely shredded Parmesan cheese
1 cup shredded mozzarella cheese
1 pkg (16oz) macaroni
1.) Cook pasta in large pot of boiling, salted water to desired tenderness. Drain.
2.) In separate bowl, mix soup, cheeses & milk. Stir in cooked pasta. Pour into greased casserole dish & cover.
3.) Bake at 325 degrees for 45 minutes.
