Slow cooker batch cook.
put into plastic reusable take away tubs and freeze.
I tend to chuck in extras so anything at the bottom of the fridge about to go off, chop up and throw in, bulk up with lentils, chick peas stuff like that.
I’ve bolognaise, veg curries, macaroni cheese in the freezer at the moment, in single tubs so everyone can choose what they want.
Big bags of frozen fruit and veg, especially on offer.
A whole chicken thrown in the slow cooker makes 2 meals in our house. Roast dinner or chicken wraps and a Home made chicken pie with left overs.
Something on toast one night, poached eggs or beans.
We “eat out of the freezer” one night a week, so throw whatever is in there towards a meal, it’s a free meal really.
Meal plan for the week and shop according to what is on that list. Saves a lot of money.
