I've posted this recipe before but I think it's one of my favourites. I tend to mix it up slightly based on what veg and herbs and spices I have in the this is the original recipe:
1 onion, peeled and finely chopped (I got a bag of the precut onions from asda and just chucked the whole packet in)
1 red pepper, diced (I used two this time)
2 large skinless and boneless chicken breasts, cut into thin strips
800g canned chopped tomatoes
400ml chicken stock - I used 3 stock cubes to make sure it was relatively thick
1 tbsp chopped rosemary
1 tbsp crushed chillies
2 tbsp. tomato puree
Finely grated zest and juice of 1 lemon
Salt and freshly ground black pepper
I also chucked in a packet of cherry tomatoes (halved and quartered) as they weren't going to get used otherwise.
Place the onion and pepper in a large non-stick saucepan and stir-fry for 4-5 minutes.
Add the chicken, tomatoes, stock, rosemary and lemon zest, chillies and juice.
Bring to the boil, stir, then cover and simmer on a medium heat for 20 minutes, stirring occasionally.
Season to taste and serve
