Heat one tablespoon of the olive oil in a large skillet over medium high heat. Add the onion and sauté for 5 minutes until starting to soften.
Add the broccolini or broccoli and sauté for 7 minutes until the broccolini starts to soften. Add the jalapenos and corn and sauté for another two minutes. Add half the zest and stir to blend.
Turn the vegetable mixture into a serving bowl. Sprinkle with the remaining lemon zest. Serve hot.
Notes
Broccolini is related to broccoli though milder in flavor. Its stalks are longer and slimmer and the heads are much smaller. It’s a cross between regular old fat-topped broccoli, and a type of Chinese broccoli called gai lan or jai lan. Feel free to use chopped regular broccoli in place of the broccolini if that’s easier to get ahold of. Broccoli rabe, which has a pleasing bitterness, would also be a great choice.
