Preheat oven to 375 degrees F and line a baking sheet with parchment paper.
Place 1/2 small onion, garlic, raw pumpkin seeds, coconut aminos, olive oil, salt, pepper and red pepper flakes in a food processor or blender and pulse until well combined into a paste.
Place the ground beef, ground pork, the pumpkin seed paste, the potato flakes, parsley and oregano into a large mixing bowl and combine everything with your hands until the ingredients are evenly distributed, but do not over-mix.
Form into about 24 meatballs, about 2-inches each in diameter, and space them out evenly on the parchment-lined baking sheet.
Place the sheet in the oven for about 15 minutes or until they are cooked through.
Prepare the spaghetti per the package instructions while the meatballs cook and you make the sauce.
