Good friends, good times taco dip (this was the name they gave it at a restaurant I used to work at)
take three big (heaping) tablespoons of cream cheese
mix with four (heaping) tablespoons of sour cream
add in either Taco seasoning mix, or Chili seasoning mix (comes in a packet)
Blend until creamy, spread onto a plate evenly, like a paste on the bottom.
Shred lettuce and pile on top, cut one tomato into cubes and sprinkle on top. Put a blob of salsa in the very middle.
Eat with tortilla chips.
It's REALLY good (made it last night), and if you want you can do a reduced fat version with the sour cream and cream cheese and it still tastes great. It's also exceptionally easy to make.
