Step 1: Heat a large frying pan over a medium heat. Add the beef mince and cook for 7–10 minutes, breaking it up with a spoon until browned throughout. Drain any excess fat.

Step 2: Stir in the taco seasoning and water. Bring to a gentle simmer and cook for 5 minutes, stirring occasionally until thickened.

Step 3: Lightly crush the tortilla chips inside their bags. Carefully cut open the side of each bag.

Step 4: Divide the seasoned beef between each bag, then top with the shredded lettuce, Mexicana Grated, diced tomato, sour cream and salsa.

Step 5: Serve immediately in the bags with a fork and enjoy.
