I tried these a few weeks ago for an afternoon of Sunday football.  Surprisingly easy and good!

From Tasteofhome.com Meatballs in Barbecue Sauce

Ingredients
1 Egg, lightly beaten
  1 can (5 ounces) evaporated milk
  1 cup quick-cooking oats (panko will work too!)
  1/2 cup finely chopped onion
  1 teaspoon salt
  1 teaspoon chili powder
  1/4 teaspoon garlic powder
  1/4 teaspoon pepper
  1-1/2 pounds ground beef
  SAUCE:
  1 cup ketchup
  3/4 cup packed brown sugar
  1/4 cup chopped onion
  1/2 teaspoon Liquid Smoke, optional
  1/4 teaspoon garlic powder

1. In a large bowl, combine the first eight ingredients. Crumble beef over mixture and mix well. Shape into 1-inch balls.

2. Place meatballs on a greased rack in a shallow baking pan. Bake, uncovered, at 350° for 18-20 minutes or until meat is no longer pink; drain.

3. Meanwhile, combine the sauce ingredients in a saucepan. Bring to a boil. Reduce heat and simmer for 2 minutes, stirring frequently. Pour over meatballs. Bake 10-12 minutes longer. Yield: about 4 dozen.
