I did start by frying a chopped onion in some olive oil, but that's where the cooking ends!
To that I added a spoonful of chipotle paste, a tinof drained kidney beans, ditto haricot beans, and a tin of tomatoes with garlic.
It simmers on a low heat for 20 minutes or so and that's it.
To make the wraps, I started with little gem lettuce, then sour cream, the beans and finally, grated cheddar.
As you'll see I'm rubbish at actually wrapping them!
