Remove the tough stems of the greens and spinach and rinse then spin in a salad spinner to remove excess water
In a food processor, pulse the greens, garlic, cashews and salt, scraping down the sides
Slowly add the olive oil while the food processor is running, then pulse until it is a smooth consistency. You may need to add some water to create a smooth consistency. Taste and add additional salt, lemon juice or olive oil
