Puffed Rice (a.k.a. Rice Krispies) is a great substitute for bread crumbs.
I discovered this last week when I made Asian chicken patties. Then I tried them in salmon patties.
It's patty mania. Anything else I can form into a patty?
It was oddly amusing that the patty mixture was snap crackle and popping. It turned out very good.
So from now on I will use puffed rice in my patties. Patties are great because they cook very fast, which I like. I don't really follow a recipe so I make it up as I go. But the general rule of thumb is to have a pound of meat and an egg to make it stick, but the rest is up to you.
