Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large bowl, combine the ground meat, chopped bell peppers, chopped onion, breadcrumbs, cheese, egg, garlic powder, cumin, chili powder, salt, and black pepper. Mix until just combined; be careful not to over mix.

Using your hands, form the mixture into small meatballs, about 1 inch in diameter, and place them on the prepared baking sheet.

Bake in the preheated oven for 18-20 minutes, or until the meatballs are cooked through and reach an internal temperature of 165°F (75°C).

Let the meatballs cool slightly before serving. Enjoy!
