In a large skillet, cook the 1 pound of lean ground beef over medium heat. Use a wooden spoon to break it apart while it cooks. Continue to sauté until it’s browned and fully cooked, which should take about 5-7 minutes.
Once the beef is cooked, add 2 tablespoons of taco seasoning mix to the skillet along with 1/2 cup of water. Stir well to combine. Let it simmer for about 5 minutes, or until the mixture thickens slightly. Remove from heat and set aside.
While the beef is simmering, chop 4 cups of romaine lettuce and place it in a large mixing bowl. Add the diced tomato for a fresh burst of flavor.
To the bowl of lettuce and tomato, add the cooked ground beef mixture, 3/4 cup of shredded cheddar cheese, and 1 1/2 cups of slightly crushed Doritos. Toss everything together gently to combine.
Drizzle 1/2 cup of your favorite light salad dressing over the salad. Toss again to ensure everything is coated evenly.
Once everything is combined, transfer the Doritos Taco Salad to a large serving bowl. Enjoy it fresh and crunchy!
