http://thepioneerwoman.com/cooking/2010/12/meatballs-with-peppers-and-pineapple/

Meatball Ingredients:
1 1/4 pound ground beef
1/2 onion, diced very finely
1 egg
1/2 cup Panko bread crumbs (or regular breadcrumbs)
1 tsp Kosher salt
Freshly ground black pepper
1/2 tsp crushed red pepper, or more to taste
1/4 cup all-purpose flour
Canola oil, for frying

Sauce Ingredients:
2 green bell peppers, seeded and diced roughly
1 1/2 cups fresh pineapple chunks
2 cups beef stock or broth
2 Tbs soy sauce
1/2 cup sherry or white wine vinegar
1/3 cup sugar
1 Tbs cornstarch
Salt to taste
Crushed red pepper to taste
Extra beef stock, if needed

Preparation Instructions:

Combine ground beef, diced onion, egg, salt, pepper, breadcrumbs, and crushed red pepper. Mix with hands until combined. Roll meat mixture into small balls and place on a cookie sheet. Freeze on the pan for 15 minutes to firm.
Mix together beef stock, soy sauce, sherry (or vinegar), sugar, and cornstarch.
Heat canola oil over medium-high heat. Roll meatballs in flour, then fry in two batches until nice and brown, about two minutes per batch. Remove meatballs and set aside on a separate plate.
Pour off oil from pan and return pan to medium high heat. When pan is hot, throw in the chopped green peppers and cook for one minute. Add pineapple to pan and cook for one minute, stirring gently. Pour in stock/soy sauce mixture, then add meatballs. Stir gently to combine and allow to cook and bubble for a few minutes, or until sauce is thickened. Add salt and crushed red peppers to taste. (Hint: this dish is yummy if it’s a little spicy.)
Serve over cooked brown or white rice.
*We used apple cider vinegar
*We took out meatballs and sauce for Miriam before adding crushed red pepper. We like spicy food.
