It was very good although next time I will double the amount of corn flakes. This recipe is a keeper!

Excellent, easy and with a quick mix of the ingrediants, your hands are free to complete the main meal. I added some chopped green/red bell peppers and 1/4 cup minced green onions, which added s...
