Sweet and Sour Meatballs

1 (15 oz.) can crushed pineapple
1 (15 oz.) can tomato sauce
1/4 cup cider vinegar
2 tablespoons brown sugar
2 pounds lean ground beef
1/2 cup dry bread crumbs
2 eggs, lightly beaten
1-1/2 teaspoon chili powder
1/2 teaspoon ground cumin
1/4 teaspoon salt
1 teaspoon parsley flakes
Vegetable oil

Directions:
Combine pineapple (with juice), tomato sauce, vinegar, and sugar in a 3-quart saucepan. Bring to the boiling point, stirring as needed to prevent sticking. Remove from heat, cover, and set aside. Combine ground beef, bread crumbs, eggs, chili powder, cumin, salt and parsley in a zippered plastic bag. Squeeze out air and close bag securely; knead the bag to mix the ingredients. Shape small meatballs using 1 tablespoon of meat mixture for each one. Coat the bottom of a heavy skillet with vegetable oil. Over medium heat, brown the meatballs on all sides. Add meatballs to sauce. Reheat; simmer for 20 minutes (stir gently as needed to prevent sticking). Serve over hot rice.
