Oh, dear, shades of the year my mom got a huge box of chicken patties and we ate them every which way.
I assume they're ground or cubed and breaded?
Use them as the meat in almost any schnitzel-type dish. (veal Oscar, viener snitzel, jaeger schnitzel, etc).
Slice thinly and use in a stir fry.
Midwestern-style, on a bun like a hamburger.
We had so many of the darned things that Mom finally threw up her hands and threw them in a meat grinder, added mayo, pickles, onions, etc and turned them into a sandwich spread.
Layer in a baking dish with cheese (mozerella, parm) and tomato sauce, and bake until warm.
Thinly sliced or chopped up, they can be the meat in any casserole dish.
