Heat a large pan over medium heat and add the olive oil and onion. Cook for 2-3 minutes, until onion is softened. Add the garlic and cook another minute or 2, until fragrant.
Add in the kale, white beans and lemon juice. Season with salt and pepper, to taste, and cook until everything is heated through. I like to leave my kale with some texture so I don’t cook it all the way down.
Enjoy by itself, on toast, with rice or however you prefer!
