Walking Taco Casserole with Fritos has all of the fun of your favorite traveling tacos, baked into a meaty, cheesy casserole with a lettuce and tomato topping.
For a spicier version, consider adding diced jalapeños to the beef mixture or using a spicier taco seasoning. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
