In a non- stick pan, heated over medium-high add the ground beef and sprinkle with the taco seasoning. Cook the beef using a spoon to break it up as it cooks aprx. 10 minutes.
Once cooked, strain the liquid and put the beef in a bowl to rest and cool
Once the beef is at room temperature (10 minutes), in a large bowl add the beef, Catalina dressing, and Roma tomatoes together mixing with a spoon to fully combine. Refrigerate for 1-2 hours to allow mixture to come together.
Refigerate the mixture covered for 1-2 hours and upto 1 day.
Before you are ready to serve, remove the beef mixture from the refrigerator, let it sit out for 15-20 minutes.
While beef the mixture is coming to room temp prep the lettuce.
Remove outer leaves from the Iceberg Lettuce and slice the head in half and then into quarters. Cut the lettuce into thin shreds. Wash and dry the shredded lettuce. A salad spinner makes this easy, but a strainer works nice as well
Leaving the Doritos in the bag, poke a hole in it with a knife to allow air to get out. Using your hands or a rolling pin gently crush the entire bag until they are small bits.
Add the crushed Doritos to the lettuce, cheese and beef mixture.
Add the Taco Cheese and remaining Catalina dressing.
Using a wooden spoon mix all ingredients togethr until fully incorporated.
Serve immediately.
Notes
For maximum freshness serve this immediately after mixing all ingredients. The Doritos and lettuce are best when there is a crunch so they should be added last.
When making a batch for a small group (we make it for 2 all the time). Mix it ready to eat as needed. We keep the fresh lettuce shredded in the refrigerator and add Doritos as we make it.
Crushing the Doritos in the bag will save your hands from turning orange!
