My wife makes a mean macaroni and cheese (with ham). She also makes a great ham soup (broth, vegetables, ham and noodles). She makes these every time we have leftovers. She freezes both too so we can have either whenever we want.
You could make ravioli with it. Or better yet, fry it up with a nice crispy like you do to make cutlets. I wish I had your problem. I didn't make as much ham as I should've. I made just enough for two meals, but not enough to have an abundance of leftovers. I have serious regrets now.
I was going to say to freeze it and pull it out later when you aren't sick of it. Fried ham and eggs is a favorite for us. @Gardenry can you share the recipe for the ravioli? Would you use ham or turkey? It sounds delicious!
