Nasturtium Pesto

Introduction
Nasturtiums grow everywhere in this country, and some gardeners even regard them as weeds. I always let them have a section of my back fence because they are great pest deterrents and I recently discovered they are great to eat.
Serves: 4
Ingredients
4 cups nasturtium leaves
6 cloves garlic
1½ cups extra virgin olive oil
2 fresh chillies, finely chopped with seeds
1 cup walnuts
Salt to taste
