This was very good. I used Cajun sausage, and a Cajun seasoning along with all of the peppers and onions.
It is a “make again” recipe, but I will cut the peppers and onions into smaller pieces.
Sandy Rinne
Awesome dish! I used sausage stuffed with jalapenos & cheddar cheese (daughter likes a bit of spice!) Used creole seasoning (what I had), added pepper flakes, & served it over riced broccoli. Daughter loved it!
