Wash kale leaves well and squeeze out any excess water. Zest and juice the lemon. Add the kale, lemon juice, 1/2 tsp lemon zest, Lemon Basil Balsamic Vinegar, Greek Basil & Garlic Olive Oil, garlic, walnuts, Parmesan, 1/2 tsp salt, and 1/4 tsp black pepper to a food processor. Pulse and process until the mixture is well blended and looks like pesto. Taste and adjust seasonings if needed.
