Toss together the cabbage, lime juice, coriander and 1/2 tsp salt in a bowl, then set aside.

Heat the oil in a non-stick frying pan over a medium heat. Add the chorizo and fry for 5 mins, then tip in the onion and pepper along with a pinch of salt and fry for 7-10 mins, or until the onions are golden and the peppers are beginning to soften. Stir in the garlic and paprika and fry for a further minute. Add the pinto beans and roughly crush half of them in the pan with the back of a wooden spoon. Season well and stir everything together.

Warm the tortillas through in a dry frying pan over a medium heat for around 30 seconds on each side. Fill with the bean mixture, red cabbage and the avocado.
