I like to take a big bowl. Throw everything in there. Your sausages, vegetables. I used asparagus, mushrooms, onions, peppers,garic & squash. Cut stuff into bigger pieces/chunks. Add some vegetable oil. Rosemary, oregano, Italian spice, crushed chilis (optional). Mix it all til well incorporated.
I then pour it all into my cast iron frying pan. Foil and bake 350 for about 45 minutes to an hour. I do stir half way threw. For the last 15 minutes I cook with foil off.
