pound them with a meat mallet (or any other hard implement, like a rolling pin) to thin them out, dip them in egg then breadcrumbs, lightly brown in a frypan on each side, then top with tomato pasta sauce and cheese, then bake in the oven for maybe 20 mins or so and you have chicken parmigiana. Or you can skip the topping, and just fry them and you have chicken schnitzels. Cut them into small pieces, dip in egg and breadcrumbs and bake and you have chicken nuggets. Or you could just marinate them and bake.
