If you want to do a roast then you can do the meat in a slow cooker, you literally switch the SC on, put the meat in, put the lid on and leave for 4-5 hours.
For 'roast' potatoes boil potatoes, once cooked fry, ideally deep fry, but you could do them in a frying pan.
Other veg just boil / steam.
to make gravy, remove the meat and wrap in foil to keep warm and use the juices to make a roux, add boiling water and a stock cube.
Another SC recipe i2 pork hocks, 1 or 2 per person put them in the SC with the widest part down and the bone at the top. Add a 50/50 mix or cider and boiling water. After 4-5 hours cook your veg, then use the cider/water to make a sauce.
Simple pasta recipe. Pasta, cream cheese, salt and pepper with optional mushrooms, smoked salmon, onion etc.
Put pasta of choice in a pan, I tend to use tagliatelle because it is in 'nests' and you can use 1 or 2 per person (3-4 for a teenage boy)
Once the pasta has cooked turn it off but leave in the pan.
If you are using onion or garlic or mushrooms fry them in butter in a large frying pan. Once cooked add the cream cheese, I use a 'dollop' for me but for a family you can put the whole tub in. Add a few tablespoons of the pasta cooking water and stir.
Once you have melted the cheese drain the pasta and add it to the frying pan, stir through and serve.
You could use passatta instead of cream cheese to make a tomato sauce.
