7-UP Meatloaf

2 lbs. ground beef
2 eggs, slightly beaten
1 1/2 c. breadcrumbs
3/4 c. ketchup
1/2 c. 7-UP
1 envelope dry onion soup mix (I've also used onion mushroom and beef mushroom)
1 (8 oz.) can tomato sauce

Combine all ingredients except tomato sauce in bowl; mix well. Place in a shallow baking pan and shape into a loaf. Top with tomato sauce. Bake at 350 degrees for an hour.
