Mexican nacho casserole
Preheat the oven to 200°C/ 400°F/Gas mark 6.
Cook the minced beef and herbs in a frying pan, mixing well and stirring to break up any lumps.
Spread the refried beans in the bottom of a medium casserole dish, then sprinkle with the onions. Layer the meat over the beans. Bake in the oven for 15 minutes.
Tuck the nacho chips around the edges of the casserole, then top with the pepper and cheese, and bake for a further 5 minutes. Serve immediately
