We use a slow cooker both at home and in the caravan - they are just brilliant.
Made a Delia 'sausages in cider' last weekend, when we had the snow. I think that's what is called comfort food - the slow cooker it cooked to perfection.
Steve's favourite is roast pork - I cook it in the slow cooker for ages (doesn't really matter how long, as long as it's cooked through), then blast it in the oven with the roasties to crisp up the crackling. Result - soft and tender meat and crispy crackling mmmmmmm
Steak and kidney pud is good too, and any sort of casserole type things, they come out with lots of lovely gravy, and the meat is really tender. We have a proper butchers in town and can get cuts of meat probably not available in supermarkets - skirt and brisket for example, which are (relatively) cheap and ideal for slow cooking.
I know I'm raising this from the dead but I actually bought one of these after reading the comments posted here, it's become the way we cook most of our meals as they are really tasty and economical meals.
I fill the pot to the rim which gives us the meal on the day and 4 double foil storage containers for the freezer.
Linda likes my slow cook lamb
Leeks, Parsnip, Potatoes, carrots, Onion, noisette of Lamb, mixed herds, and a combination of Vegetable, beef and chicken oxo.
The only draw back was the real pain for me of dicing the vegetables until I came across The Nicer Dicer from JML I picked mine up from MACRO for £16 + vat. You can see them advertised on ebay for cheaper but they are not the same product and break quickly according to the reviews here
