Usually I don't have luck growing basil - it regularly goes to seed before I can harvest much. But this year I have a really good crop and all I can think is - Pesto! Far from innovative, pesto is still such a classic and a crowd pleaser. I make mine in a blender and the whole thing is done in minutes.
Put about 2 cups loose basil leaves in blender. Add 2 cloves pressed garlic, 3/4 cup pine nuts, 3/4 cup grated Parmesan, 1 cup olive oil, and salt to taste. Blend all ingredients and it is ready to go.
I keep a jar of pesto in the fridge for a quick pasta dinner, but the sauce is also great on a sandwich, or grilled halibut.
