When the nuts and seeds are room temperature, add them to the bowl of a food processor along with the basil, baby spinach, Romano, garlic, Limoneira Meyer lemon zest and juice, salt and pepper.
Pulse a few times, until the ingredients begin to come together.
Add 3/4 cups of the oil in a steady drizzle as the processor runs at a medium to slow speed.
After the last of the oil has been incorporated, stop processing and use a rubber spatula to scrape down the sides of the bowl.
Continue processing until the ingredients are fully blended.
Add the last 1/4 cup of oil at a drizzle, until it’s at the desired consistency. If you prefer thicker, you may use very little of the last 1/4 cup.
Transfer to a jar, and spoon another tablespoon of oil on top of the mixture before you add the cap.
It can also be stored in the fridge in any covered container for up to 5 days.
You can freeze it in a sealed container for up to 3 months.
