Italian Bake

8 ounces pasta (I usually use the bow tie or the spiral ones, not sure what they're called.)
1 jar spaghetti sauce
1 envelope Italian salad dressing mix
1 lb. ground beef or chicken
2 cups grated mozzarella

Cook pasta according to package directions, drain. Cook the hamburger or chicken. (If you're using chicken, cut it up into bite sized pieces.) In a bowl, combine the spaghetti sauce and salad dressing mix; add pasta and mix together. Place the meat on the bottom of a casserole dish. Spread the sauce/pasta on top. Sprinkle with cheese. Bake, uncovered at 400 degrees for 15-20 minutes or until heated through.
