Family taco pie

Preheat the oven to 200°C, gas mark 6. Heat 1 tsp oil in an ovenproof frying pan or wide, flameproof casserole. Fry the pork mince over a high heat for 5 minutes, until turning golden. Add the onion and frozen vegetables. Keeping the heat high, cook for 8-10 minutes, until the pork has browned with no pink meat and the vegetables are soft.

Pour in the tomatoes and the kidney beans, season, then cover and simmer for 10 minutes until rich and thick.

Brush 1 side of each tortilla with a little of the remaining oil, stack, then cut into 8, like a cake. Scatter the tortilla triangles over the chilli, oil-side up. Bake for 10 minutes, or until the mixture is bubbling and the tortillas are crisp. Scatter with the avocado and coriander and serve with lime wedges.
