This was one of my "throw in what you've got meals". After dusting the larger pieces of chicken for the adults I put another 1/2 cup of bread crumbs into the spice mix & dusted the smaller breast pieces in the less spicy mix for the kids.
Cook the first medallion and test for thoroughness of cooking & moistness. If it falls apart then it is probably too moist. Remedy this by adding an extra tablespoon of cornflour to the mix and cook another one. Repeat until medallions hold together. Also, run a knife around the edge of the medallions to remove the rings when cooked.
