Once a year, my mom would always make "Hot Rolls" from a box mix and we would eat turkey sandwiches for the next few days. Love them. I love turkey tetrazzini (could be ham tetrazzini) and turkey enchiladas. I might try a turkey and rice casserole this year.
I find it hard to repurpose the veggies -- I just reheat them and eat as is.
