Have a look at the batch lady website. She does a lot of grab bags as well as cook ahead and freeze stuff - so the idea is that everything is just sitting waiting for you in the freezer, you defrost it, tip it into the oven and cook it.
As well as curries, Bolognase and stews, I freeze bags of simple tomato sauce. When I get a veg box, I get the food processor out and chop onions, celery, garlic and carrots and freeze it in small bags as often it's the standing chopping that takes up time (and needs two hands!).
It's also about buying smart - there is so much great freezer stuff available now. Chopped peppers, onions, spinach, garlic, ginger, herbs. Also potato products - croquettes, frozen chips, potato rosti.
So batch lady method would say: get a big box of chicken breasts and freeze them individually with oil, lemon, salt, pepper, spices you like. When you want to eat them, defrost over night then tip onto an oven tray. Heat up the frozen potato product of your choice. Boil some peas from the freezer or give some peppers and garlic a quick stir fry. It's as much about thinking of your freezer as a stock cupboard as cooking big batches.
