Creamy Basil Walnut Pesto

In a food processor: process the basil, garlic and walnuts until smooth. Slowly add the olive oil (through the top opening) while running it. Last, add the grated cheese, lemon, sea salt + pepper and pulse again. Do a taste test and add more sea salt/lemon if needed. Store in a sealed glass container in your fridge! Top with a little bit of olive oil before closing it to create another air seal and keep it from drying.
