i could not survive if i didn't batch cook.
i also could not survive without my slow cooker.
slow cooker recipes are very easy and simple:
meat (beef, chicken, pork)
onions
booze (red, white, cider)
I might add some root veggies but very large chunks to avoid disintegration.
cook for 6 - 8 hours and thicken with gravy granules or soured cream/yoghurt etc.
I use braising steak and chicken thighs for the slow cooker as not only are they cheap but they work well with slow cooking.
Other recipes I batch cook are:
spag bol (spag and bol go in freezer!)
cottage pie, put handfuls of frozen mixed veg in too.
lasagne
salmon and broccoli in a cheese sauce
mashed potatoes
rice
chicken/lamb curry
chicken/beef sweet chilli stir-fry
i also freeze extra portions of roast veggies like parsnip, sweet potatoe, carrot and potatoe tossed in olive oil with paprika and roast from frozen with a joint or chicken.
i am also a tupperware queen, actually i am an "any sort of container that will go in the freezer freak"!
