1cupof grated pecorino or parmesan cheese(I used a bit of both as I was finishing off what I had in the fridge)
1/2cupwalnuts(you could use pine nuts, hazelnuts or slivered almonds)
juice of half a lemon
Salt and pepper to taste(about half a teaspoon is good)
Instructions
Place all ingredients in a food processor and process until it reaches a pesto consistency. If it is a little dry add some additional olive oil while the machine is running or you could add a couple of tablespoons of water
Notes
Place into sterilised jars and keep in the fridge for about a week. Alternatively freeze in ice cube trays and take a couple of cubes out when needed
