Looking at that list, I'd make a veggie pasta bake either with a tomato base or roux base if you have butter, flour and milk.

My freezer always has portions of meals I've made double batches of. eat one the day it's made and freeze one. Faves are bolognese sauce, Irish stew, beef stroganoff, Penang curry, sausage tomato and eggplant casserole, pork and cider casserole, that sort of stuff!
