Make the meatballs: In a large bowl, combine 1 pound of ground turkey, 1 chopped onion, 2 minced garlic cloves, 1 chopped scallion, 1 large egg, 3 tablespoons of breadcrumbs, 1 tablespoon of sesame seeds, a handful of fresh chopped cilantro, and salt and pepper to taste. Mix well until all ingredients are fully incorporated. Shape this mixture into meatballs of your desired size and place them on an oiled baking sheet. For a firmer shape, you can freeze the meatballs for about 10 minutes.
Bake: Preheat your oven to 410°F (210°C). Bake the meatballs for 10-12 minutes until they turn golden brown and are thoroughly cooked. You can check for doneness by cutting one meatball in half to ensure it's no longer pink inside.
Make the sauce: In a separate skillet, whisk together 1 cup of pineapple juice, 4 tablespoons of low sodium soy sauce, 4 tablespoons of tomato paste, 2 tablespoons of cornstarch, 1 tablespoon of molasses, 2 tablespoons of honey, and 1 tablespoon of sesame oil (if using). Stir in 1 cup of diced pineapple. Bring the mixture to a gentle boil, then reduce the heat and let it simmer until thickened, stirring occasionally, for about 5-7 minutes.
Finish up: Once the meatballs are cooked, add them to the skillet with the sauce over low heat. Gently toss the meatballs until they are well-coated and glazed with the sauce. Allow them to heat through for an additional 2-3 minutes.
This dish is best served immediately to enjoy the full impact of the flavors, but it will also make delightful leftovers!
