Combine all three ingredients. You can add taco seasoning if it needs it.
You might also want to squeeze some lime into the dressing.
Taco Salad
Arrange lettuce, meat, cheese, avocado, olives, tomato on plate and use dressing as much or as little as you like.
Notes
I use Trader Joe's fire roasted salsa, which has just the right kick. If you are using a jarred salsa that is not spicy, you might want to add some taco seasoning.
