Equal parts cream cheese and sour cream (I use 16 oz. of each for large dish.)
1 pkg. taco seasoning
Tomatoes, chopped
Lettuce, chopped
Cheddar cheese, grated

Cream the sour cream and cream cheese together. Add taco seasoning to your own taste (small amount for mild - more for hotter). Spread on plate. Arrange tomatoes, lettuce and Cheddar cheese on top in layers. Serve with taco chips.
