This is adapted from another recipe I found. We love it. I am sure it would be good with beef too, but we use turkey breast because it is so much lower in fat. We serve these on a wheat bun with mayo and tomato....maybe some fries on the side...good stuff! Since 1/4 of a red bell pepper is such an odd measurement, I will freeze the other 3/4 of the pepper so I can just pop it out when I need it. They freeze really well and you can chop them straight out of the freezer.
