Mine is chicken casserole:
2 carrots
1 onion
1 or 2 courgettes
1 carton of tomato passata
1 500g pack of fresh chicken thighs (frozen)
I chop veg and put in large casserole pot, tip passata over and then frozen chicken on top. Put in at 160/170 for 4 hours
Serve with pasta and sprinkle grated cheese
I sometimes add wine/pepper/garlic. But even without its yummy
