Pulse the garlic in a food processor until finely chopped, then add the kale, walnuts, and Parmesan cheese. Pulse until chopped, turning off periodically and removing the top to press the kale down toward the blade if necessary.
With the food processor running on low, pour the olive oil in in a steady stream until it forms a sauce. Add the lemon juice and pulse a couple more times.
Scrape down the sides and add the beans, along with a pinch of salt and pepper. Puree, adding more oil if necessary to obtain a smooth consistency. Taste and add additional salt and pepper if desired.
Transfer to a bowl and top with additional almonds and a drizzle of olive oil if desired. Serve with pitas, crackers, and/or veggies.
