Add ground beef to a large pan over medium-high heat. Use the end of a wooden spoon to break up the ground beef into smaller pieces. Continue to cook until beef is browned and no longer pink. Drain the fat from the pan.
Add the chili powder, paprika, cumin, cayenne, oregano salt, pepperand water to the pan with the beef and mix well to flavour the beef evenly. Continue to cook, stirring occasionally, until the water has evaporated and you are just left with the seasoned beef. Remove from heat and set aside.
In a small bowl prepare the dressing by adding the oil, vinegar, Worcestershire, ketchup, soy sauce, paprika, onion powder, garlic powder, salt and pepper to a small bowl. Whisk until smooth and well blended.
Add the iceberg lettuce, tomatoes, red onion, and beef to a large bowl. When ready to serve pour the dressing over the salad and mix well. Add in the broken corn tortilla chips and mix. Do not add the chips until you are ready to serve or they will become soggy.
Notes
Only add the salad dressing and chips just before serving to prevent the lettuce and tortilla chips from becoming soggy.
