Preheat oven to 375 degrees F and line a baking sheet with parchment paper or grease it with nonstick cooking spray and set aside.
Add sausage, baking mix, onion, garlic powder and cheese in a mixing bowl and mix well. It's stiff and hard to incorporate everything at first, so use your hands to mix it all together.
Using a 2 tablespoon sized portion scoop, scoop sausage into balls and roll them in your hands. Place onto prepared baking sheet about 1" apart.
Bake for 15 minutes or until golden brown. Remove from oven and remove from baking sheet. Serve immediately.
