A mixture of chicken, eggs, bread crumbs, sauteed onion, parsley and light seasoning make croquettes you'll go crazy for! My grandmother used to make salmon cakes; I adapted that recipe to use leftover cooked chicken.
Easy Chicken Croquettes from Food.com: Our Oh-so-yummy and EZ-to-make croquettes! These are great for OAMC too. The croquettes freeze well, then just pop them in the microwave for a quick meal or snack. Does not include 3 hr chill time. Cone shape is traditional for croquettes, but I have made patty shaped ones that are just as wonderful. Try adding some chopped mushrooms too. Thanksgiving leftovers?..
