This is a sauce that can brighten up nearly any dish or used as a dip by itself. This recipe has a strong lime flavor. If you would like to tone down the lime a bit, use 2 or 3 limes rather than 4.
 
4 Avocado
4 Limes
14 oz Sour Cream
1 Bunch Cilantro
 
Blend until smooth, then top your favorite dish.
