Preheat the oven to (180C) gas mark
In a heavy based pan soften the onions and celery in the olive oil.
Add the red pepper, garlic, tomatoes, 1 tbsp of tomato pure and the stock, then bring to a simmer.
Add the spices and taste for seasoning.
Add extra chilli if you're feeling brave, and to help ward off a winter cold.
Simmer to let the flavours develop for about 10 minutes.
Next, drain most of the liquid from the pan.
Bake for 15 minutes or until the cheese is browning and the sauce is bubbling.
