Meatballs: 1 pound ground beef ¼ cup bread crumbs 3 tablespoons soy sauce 2 tablespoons brown sugar 2 tablespoons garlic, minced 2 large egg whites Sauce: 1 (15 ounce) can crushed pineapple ½ cup soy sauce ¼ cup brown sugar 1 pinch garlic salt, or to taste ground black pepper to taste 2 tablespoons cornstarch ½ cup cold water Directions Instructions Checklist Step 1 Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with foil. Step 2 Mix ground beef, bread crumbs, soy sauce, brown sugar, garlic, and egg whites for meatballs together in a bowl until well combined. Form into 1-ounce balls. Transfer to the prepared baking sheet. Step 3 Bake in the preheated oven for 25 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (71 degrees C). Step 4 Meanwhile prepare sauce: Combine pineapple, soy sauce, brown sugar, and pepper in a saucepan over medium heat. Bring to a boil, then reduce to a simmer. Step 5 Mix cold water and cornstarch together in a small bowl; add to the sauce. Stir and simmer until desired thickness, 3 to 5 minutes. Add meatballs and cook until heated through, about 5 minutes.
