How to Make It
Preheat oven to 400°F. Toss 3 bunches Broccolini with 4 tablespoons oil, ½ teaspoon salt, and several grinds of pepper on a rimmed baking sheet. Arrange in a single layer and roast, shaking sheet halfway through, until charred in spots, 12 to 15 minutes.
Meanwhile, thinly slice half the lemon. Stack slices and finely chop. Transfer chopped lemon (including peel) to a food processor and add the juice of the remaining lemon half, honey, remaining 2 tablespoons oil, and remaining ½ teaspoon salt; process until combined, about 10 seconds.
Chop roasted and raw Broccolini into 2-inch pieces and toss with lemon dressing. Serve topped with toasted pecans.
