Avocado and Basil Crema

What I am about to say to you may come as a shock:  last week I made tacos and we had no cheese.  We did have an avocado, though.  Now, I am not saying this lovely little sauce is a substitute for cheese.  But it does give you a certain creaminess that regular old sour cream doesn't.

Avocado and Basil Crema
1 avocado
1 Tbsp mayonnaise
juice of 1 lime (~2 tsp)
1 tsp minced fresh basil
1/2 tsp sea salt

   Mash avocado so it is almost smooth.  Mix in all other ingredients.
   Makes ~1 C (but it depends on the size of your avocado).  Put it over anything.
