I've used mine almost daily for the last month, here are some of the things I've done in it:
Gammon in cola, with a bay leaf and a few peppercorns (some people retain the cooking liquid for use in soups or whatever, I don't fancy it)
Pork shoulder cooked on a bed of apple wedges. Or use Apple juice/cider.
Whole chicken, no liquid. Couple of balls of foil underneath if you like to save it soaking up its own fat.
Many many casseroles, I brown the cubed meat and sauté the onions til soft first. Then chuck in whatever chopped fresh or bagged frozen veg I want.
I like skinless chicken thighs/breasts, onions, mushrooms, tinned or fresh spuds, carrots, paprika, garlic, tomato purée, chicken stock, Worcestershire sauce, s+p, white wine, thyme & bay leaf for chicken chasseur type thing.
Corned beef hash: Corned beef, diced onion, cubed potatoes, tomato purée, 2 beef oxos, water, pepper, bit of Worcestershire sauce.Tinned tomatoes, carrot or swede are all optional, I actually like it best with no extras.
I made a lovely thick soup the other day, large onion, bit of celery, lots of peeled sweet potatoes, carrots, tin of chopped tomatoes, a few tomatoes going soft in the fridge, about a cupful of red split lentils, mixed herbs, 4 bay leaves, paprika, curry powder, garlic powder, tomato puree if I'd had any. 2 chicken (or veg) stock cubes, salt, pepper and half a tub of light coconut milk. It was sweet, spicy, thick (I blended it) really nice. I hid some in some jarred tomato pasta sauce for the kids tonight. Hidden veg mwahaha!
