Mix together ground beef and Living Simples Ono A Wala Season Mix until well combined. Form into 1 1/2-inch meatballs.

Saute meatballs in a large frying pan over medium-high heat until browned, about 10 minutes. Remove meatballs to a plate, reserving the pan drippings.

While the meatballs are cooking, pour juice from the canned pineapple into a liquid measuring cup and add enough water to make 1 cup. Mix brown sugar and cornstarch in a small bowl.

Add pineapple juice and brown sugar mixtures to the warm pan drippings. Add vinegar and soy sauce and bring to a boil. Cook until sauce thickens, 2 to 3 minutes. Add meatballs, pineapple chunks, and green pepper. Simmer until meatballs are no longer pink inside, about 10 minutes.
