I started making these in the Spring of 2006 when we moved to a new house and I found a meat market with the best Italian sausage I have ever had. The sausage I use already has red and green bell peppers and diced onions in it. It is the only stuff I buy now. I cook on a charcoal grill, and it really adds to the overall flavor in a way gas just could not. Prep time does not include the time it takes for charcoal to ash over. The lid should be closed the whole time unless turning or moving the meatballs.
