Preheat your oven to 350℉ (175℃) to ensure even cooking.

Line a baking sheet with parchment paper for a non-stick surface.

In a mixing bowl, combine lean ground pork, breadcrumbs, egg, onion, garlic, half of the parsley, salt, and pepper. Mix until incorporated.

Shape the mixture into approximately 32 medium-sized meatballs and arrange them on the baking sheet.

Bake the meatballs for 20-25 minutes until they reach an internal temperature of 160℉.

While the meatballs are baking, heat a skillet over medium heat and combine cranberry sauce, soy sauce, and red pepper flakes. Bring to a boil.

Carefully transfer the baked meatballs into the skillet and stir to coat them in the sauce, heating for 2-3 minutes.

Serve the meatballs warm, garnished with remaining parsley, on a platter with toothpicks or over rice.
