I'm posting this for everyone who has asked me for this recipe. Everytime I make taco salad I also make this dressing. And this is our favorite dip for tortilla chips. If you use hot jarred or homemade salsa add more sour cream to taste. This dip is also a great base for other Tex-Mex flavors...add shredded cheddar, sliced olives, sliced jalapenos, chopped cilantro and a squeeze of lime. Ole!
