Preheat the oven to 400°F (200°C) and line a baking pan with baking paper.
In a mixing bowl, combine the ground pork with the almond flour, egg, and minced garlic.
Shape into meatballs and arrange on the lined baking pan. Drizzle with sesame oil and bake in the preheated oven for 10-15 minutes.
In the meantime, make the sauce.
Heat the soy sauce, vinegar, Erythritol, and chili powder in a skillet or frying pan and simmer for a few minutes to thicken.
Add the meatballs and stir to coat. Add a bit of water if the sauce is too thick.
Serve hot, optionally topped with chopped green onions.
