1 green bell pepper, cut into chunks
1 cup brown sugar
⅔ cup vinegar
2 tablespoons soy sauce
3 tablespoons cornstarch

Instructions

Start by draining the juice from the pineapple can into a medium bowl. You’ll need about 1 cup of juice for the sauce.

Place the frozen meatballs into a 4–6 quart slow cooker.

Add the pineapple chunks and green bell pepper pieces on top of the meatballs.

In the bowl with the reserved pineapple juice, whisk together the brown sugar, vinegar, soy sauce, and cornstarch until smooth and well combined.

Pour the sauce mixture over the meatballs, pineapple, and peppers.

Cover and cook on LOW for 2 hours. Then switch to HIGH and cook for an additional 1 hour, or until the sauce thickens and becomes glossy and bubbly around the edges.
