You're in luck I just made 25# of veal meat balls last night.
You can substitute veal for sausage, obviously.
This would be for a 1# sausauge, I am just mentally breaking it down because I can do it from 5#...
1/4 c. green pepper
1/4 c. red pepper
1 each shallot
1 Tbsp rosemary
1 Tbsp Thyme
1 egg
1 cup panko
S+P to taste
Mince the peppers and shallots, saute if desired, will take away a little crunch. Add an egg and panko to bind. If it is too wet, add a little more panko. Roll the balls in extra seasoned panko for a nice crust. Cook them in oil then finish in the oven.
Protip: Before you roll them all out, take a little bit of the mixture and cook just a small sized ball to taste it first, so you don't roll it all out in bulk and not be satisfied, so test a little bit first.
Also If you use my said recipe and add 1/4 cup of parmesan cheese to the sausage mixture, it is amazing.
