Soups and cakes saw me through mat leave.
Soups I would do a tomato and lentil, country veg, broccoli abd Stilton, pea and ham, chicken- country chicken and noodle version -, French onion, cream of mushroom and butternut squash.
Single mug sized portions were a god send at 3am.
Was a pre sliced frozen loaf of banana bread ( freeze loaf cakes- lemon drizzle, ginger, Madeira, Angel, coconut, malt cake, fruit loaf, cherry, etc etc sliced and defrost in minutes in a toaster bag in the toaster....mmm warm cake)
Meals I would freeze cottage pis, chilli, chicken and mushroom pie, sausage and bean casserole, beef bourginon, lamb hot pot, corned beef pie, beef stew and dumplings ( dumplings frozen seperately)
Good luck :)
