In a large bowl, combine ground beef, breadcrumbs, egg, garlic powder, salt, and pepper. Mix until just combined, form into 1-inch balls, and place on a baking sheet lined with parchment paper.

Preheat your oven to 400°F (200°C). Bake the meatballs for 20 minutes until browned and cooked through.

In a medium saucepan over medium heat, combine cranberry sauce, soy sauce, brown sugar, and mustard. Stir until smooth and heated through, about 5 minutes.

Add the baked meatballs to the saucepan and gently toss until coated with the cranberry sauce. Simmer for 5 minutes on low heat.

Serve the meatballs from the skillet or transfer to a serving dish, garnishing with fresh herbs. Pair with rice or bread.
