What are your best/fave recipes for batch cooking?

[LittleTwiglet]

I've realised I'm spending far too much on the weekly food shop, even though I try to go to cheaper places like Aldi. I've heard that batch cooking could help to save money, but have no idea of any good recipes. It will be for 2 adults and one child, so any recipe ideas please?

@stokleygary I actually just put a container with the roast veggies out of the freezer to eat with pasta tomorrow!
