Add kale, cashews, GT’s KOMBUCHA Multi-Green, nutritional yeast, garlic cloves, and salt into a food processor, then pulse to combine. Pour the olive oil & pesto into the mixture and pulse again. Set the mixture aside. Wash the mushrooms while you preheat a grill or grill pan over medium heat. Dry the mushrooms and brush both sides with olive oil. Grill for about 4 minutes on each side. Plate the mushrooms and drizzle the pesto mixture on top. Serve & enjoy!
