Find a blend of spices and experiment until you come up with something you like. Checkout different sausage making websites for ideas.
"if your product is cooked inside another item, it will not be considered a garnish". I take that sentence to mean that you can stuff your sausage with anything you wish as long as it is cooked inside the sausage. If it were me, I'd verify that with the contest organizer and consider making a fatty stuffed with your choice of peppers/onions/cheeses/bacon...(dollar bills
)
It also looks they are going to provide the meat. I'd also find out how much meat they are going to provide before settling on a recipe.
