Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper or foil lightly greased. In a large mixing bowl, combine the ground beef, ground pork, finely chopped onion, minced garlic, chili powder, salt, black pepper, panko breadcrumbs, and 1/4 cup of BBQ sauce. Mix well until all the ingredients are evenly incorporated.

Shape the mixture into meatballs, about 1 to 1 1/2 inches in diameter, and place them on the prepared baking sheet.

Bake the meatballs in the preheated oven for 18-20 minutes, or until they are cooked through and no longer pink in the center.

Remove the meatballs from the oven and increase the oven temperature to 425°F (220°C).

Brush the meatballs generously with additional BBQ sauce, ensuring they are coated evenly.

Return the meatballs to the oven and bake for an additional 5-7 minutes, or until the glaze is sticky and caramelized.

Remove the meatballs from the oven and let them cool for a few minutes before serving. Garnish with chopped green onions if desired.

Serve the BBQ glazed meatballs as an appetizer or as part of a main course. They are great on their own, with toothpicks for easy grabbing, or served with a side of coleslaw or cornbread for a complete meal. Enjoy!
