Here is a simple, less expensive recipe for pesto:

2 cups packed basil leaves

1-2 cloves garlic

¼ cup sunflower seeds 

1/3 cup Extra Virgin Olive Oil

Salt and pepper to taste

Blend sunflower seeds and garlic in food processor enough to break up garlic well.  Add basil and olive oil and blend to desired consistency.  Add salt and pepper to taste.  Eat fresh or freeze as pesto ice cubes or pesto logs. Frozen pesto is great for soups and pasta in the winter!
