In a large bowl, add onion, baking powder, oat fiber, oregano, celery salt, parsley, sage, garlic powder, almond flour, salt and pepper. Whisk to combine.
Add sausage, eggs and cheese and stir to combine.
Form the meat mixture into equal portions and roll into a ball shape. I like to use a golf ball size as a gauge.
Bake in preheated 350º F oven for roughly 12-15 minutes or until cooked all the way through.
