Prep: Wash and trim any leaves from the broccolini stalks, and cut about an inch off the stalks. Mince the garlic and set aside.
Sauté: Warm a large skillet over medium heat and add the butter or oil until it just bubbles or shimmers. Add the garlic and sauté just for a minute until fragrant, but don't let it brown. Add the broccolini and use tongs to push and turn the stalks around in the garlic butter until they're mostly coated, sautéing for a minute or two. Add a tablespoon of water to the skillet, cover, and let the broccolini cook and steam for another minute until bright green.
Enjoy: Plate each serving of broccolini and season with a little sea salt and freshly ground black pepper. Any leftovers will stay fresh for up to two days in an airtight container in the fridge. Enjoy!
