Mild Broccolini is a crowd-pleasing vegetable; its longer stems give it a more elegant feel than regular broccoli. If you’re serving a more adventurous bunch, try swapping in broccoli rabe, broccoli’s pleasantly bitter, leafy cousin. Red pepper brings a touch of heat, and lemon zest adds a bright flavor boost. To prep, just trim the bottom inch or so from the stalks. Serve it with our Beef Tenderloin With Madeira-Dijon Sauce, pictured above.
