Y'all most likely already do this but I'll pass it along anyway. When I have to flatten something, especially chicken breasts, I take a gallon zip lock bag and put a little olive oil in it and squish it around. Then I put the breast in and pound it to the thickness I want. This also works with other meat. Before I started doing this my flatten breasts looked like they had been targets at a turkey shoot. If y'all are not already doing this you may want to give it a try. Dee
