We did chicken risotto last week including the juices from the roast - divine!!
Other favourites include:
Chicken and mushrooms in creamy sauce (with white wine if desired - alcohol cooks out), served with rice, pasta or potatoes. (Fry an onion, add mushrooms and allow to cook mostly, add cooked chicken allow to heat through. Add splash white wine, reduce by half, add dollop chick stock if need lots of sauce, add decent splash of cream, handful grated parmesan, pepper (may not need salt due to parmesan) - allow to heat through and serve). I've even been known to serve this mix between lasagna sheets or under a pastry crust as a pie. Cheat's quick version of sauce is a tin of Campbell's condensed chicken, or mushroom, or chicken in white wine, soup, but with only a splash of extra liquid.
Chicken curry made with a jar of sauce and served with rice (and readymade puppodums).
Chicken in a (jar of) tomato sauce, possibly with whatever is to hand of: a chopped red or yellow pepper, mushrooms, a sliced onion, garlic, couregette, or just frozen peas, added for extra veg - served with pasta.
Chicken reheated in leftover gravy, with freshly boiled potatoes, and steamed carrots or sugar snap peas. (I've also been known to make a pie out of chicken in gravy).
Part of a nice big Caesar salad with loads of lettuce and parmesan shavings, and a good crusty loaf (to feel substantial enough for DH).
Pasta pesto with chicken.
Spanish omelette/frittata type thing with lots of veg as well.
Nasi goreng (indian fried rice dish with lots of veg and mild curry powder).
Toasted sandwiches.
