Slow Cooked Super Bowl Meatballs

I probably won't be making this for the superbowl, because I have some vegetarians attending. However, this recipe is super easy and involves no pre-cooking.

1 16-ounce can cheese sauce (may use mild nacho cheese sauce). Velvetta pre-melted in the microwave would also work.
1 1-ounce package taco seasoning
1 14-ounce can diced tomatoes
1 1-pound package frozen cooked meatballs (plain, not Italian)

Mix cheese, taco seasoning, and tomatoes. Put meatballs in slow cooker and cover with cheese mixture. Cook on High for 1 1/2 to 2 hours.
