Cook the ground beef until it is no longer pink. Remove any grease.
Add the taco seasoning mix and water. Cook gently until it becomes thicker, for around 5 minutes. Let it cool down.
In a big bowl, mix together lettuce, peppers, black olives, pinto beans, tomatoes, cheddar cheese, and green onions.
Put the seasoned and cooled ground beef on top.
Crush the Doritos a little and sprinkle them on top. Pour catalina dressing over and mix well.
Add sour cream and more green onions if you like.
Serve right away.
Written reminders.
Mix the ingredients right before serving to prevent the Doritos from getting soft.
Have fun!
