One of my favourite meals, other than soup, is to take a whole chicken, pop a lemon and some garlic in the cavity, sprinkle outside with salt and pepper.
Peel some potatoes, cut up an onion and some carrots and put them in the bottom of the crock pot and put the chicken on top. Add 1/4 cup white wine and the same of chicken stock, put the lid on and let cook all day.
Take out the veg and the chicken when cooked and put the juice in a pot. Add a bit of flour mixed with cold water, and heat up until thickened to make the gravy. Great easy meal.
I also do it with a beef brisket just replace liquid with red wine &/or beef stock.
