Heat the oil in a large skillet over high heat until it shimmers and then heap the greens into the pan. Put a lid on the pan to help the greens wilt a little.
After 2 to 3 minutes of cooking, check to see if the greens have wilted. If so, add the garlic, beans, and cheese and stir to combine. Add a 2-3 tablespoons of water and cook for another minute or two, until the greens are tender and the liquid in the pan has coalesced into a creamy sauce.
Add the lemon juice, a little salt, and 6 or 7 turns of a pepper grinder. Taste and adjust the seasonings until you're pleased.
Serve hot or at room temperature.
