Instructions

1. Preheat the oven to 200C/400F/gas mark 6.
2. Heat the oil in a large frying pan and cook the onion and garlic over a medium heat for 3 minutes or until the onion is softened. Add the beef mince, breaking up with the back of a wooden spoon, stirring until browned and cooked through.
3. Add the kidney beans, taco seasoning mix, tomato puree and water. Bring to a boil and simmer for 5 minutes or until thickened.
4. Pour the tortilla chips into an oven-proof dish. Top with the mince and sprinkle with cheese. Bake for 15 minutes, until the cheese is golden and bubbling. Serve with tomato salsa, guacamole and sour cream.
