There are a few things that we always have a supply of.  Chocolate chip cookies is one.  The other is a big thing of pesto in the refrigerator.  The key to keeping it fresh is after using it always pour olive oil over the top so it does not spoil. 

Simple recipe:

4 cups basil leaves

1 cup grated Parmesan

1/4 cup pine nuts

1 tsp. kosher salt

2/3 cup olive oil

In a Cuisinart ( makes life easy ) put in the basil, cheese, pine nuts and salt.  Blend until really chopped.  While the blade is turning slowly add in the olive oil until the pesto becomes more like a sauce. If you need more olive oil, just keep adding until you have the consistency you want.

That's it.  Pour in a container, cover with olive oil, leave in the refrigerator for a few weeks.  It is good with almost anything.
