Make taco meat: Bring a large cast iron skillet to a medium-high heat and brown the ground beef. Drain any excess grease. Add taco seasoning and 1/2 cup tomato sauce to the meat. Simmer 10 minutes.
Mix the salad: In a large bowl add shredded lettuce, tomatoes, crushed chips (just use your hands to crush them) and cheese (if using). Add cooked taco meat on top. Mix well to fully combine.
Salad dressing: combine the remaining tomato sauce with the ketchup and taco sauce. Stir to combine in a small bowl.
Serve salad immediately with taco dressing on the side and any other desired toppings.
Notes
Leftovers: While leftovers are good, this is definitely a meal that is better enjoyed fresh. The crushed taco chips and iceberg lettuce will get a little mushy overnight in the fridge. If you do want to enjoy this salad the next day, you can store the taco salad ingredients each in a separate container.
Cheese: of course you can always use regular cheese or dairy-free cheese, if you prefer.
Paleo version: This recipe is Paleo-Friendly. Make sure you are using grain-free chips with clean ingredients (like this one), omit the cheese (dairy-free or otherwise) and when you are making your Taco Salad Dressing + Seasoning make sure you are checking ingredients.
Gluten-Free Version: This recipe is Gluten-Free Friendly. Make sure you are using grain-free chips with clean ingredients (like this one) and make your own taco salad dressing (noted in the recipe card).
