Dressing: In a bowl combine the ketchup, mild taco sauce and approx. 1/2 the can of tomato sauce. Stir and then taste. Add additional taco sauce (or toss in some hot sauce if you want), as needed. Set aside. 

Ground Beef: Bring a large cast iron skillet to medium-high heat. Add ground beef and move around until cooked through. Drain excess grease. Add the remaining 1/2 can of tomato sauce and then taco seasoning. Stir to combine. You can add 1-2 tablespoons of water to thin a bit, if needed. Turn off heat but keep pan warm. 

Build Salad: While the ground beef is cooking, add your lettuce to a large salad bowl. Add the tomatoes on top of that and then the chips. Place the cheese on top of the chips and spread out evenly to cover. 

Add Beef: Place the warm beef on top of the cheese. Let sit for 2-4 minutes so the beef can melt the cheese. Toss to combine. 

Toss and Serve: Serve immediately with the dressing and enjoy! Feel free to serve with a pitcher of Skinny Margaritas or these Beer Margaritas!
