1 can (10-3/4 ounces) condensed cream of mushroom soup, undiluted
1 cup sour cream
2 cups shredded Colby-Monterey Jack cheese
Preheat oven to 350°. Cook pasta according to package directions. Meanwhile, in a large skillet, cook beef over medium heat until no longer pink; drain. Stir in spaghetti sauce and tomato sauce. Remove from the heat.
Drain pasta. Combine soup and sour cream. In two 8-in. square baking dishes, layer half of the meat sauce, pasta, soup mixture and cheese. Repeat layers.
Cover and bake 55-65 minutes or until cheese is melted. Freeze option: Cover and freeze unbaked casseroles up to 3 months. To use, partially thaw in refrigerator overnight. Remove from refrigerator 30 minutes before baking. Preheat oven to 350°. Bake casseroles, increasing time as necessary to heat through and for a thermometer inserted in center to read 165°.
