This isn't really a salad, but the salad theme made me remember this. It always goes over very well at pot lucks, etc. Hope I'm remembering quantities right.
8 oz cream cheese
5-8 oz (small container or a bit less) sour cream
1/2 - 1 package taco seasoning (try using 1/2 the package first and add more if you think the flavor is too weak)
Place on bottom of 9" pie plate.
On top place aprox:
1 c. shredded lettuce
1/2 c shredded cheese (or to taste)
and about 1/4c-1/2 c salsa, scattered along the top.
Enjoy with tortilla chips.
