How to Make It
Preheat broiler to high. Combine whole-wheat panko, grated pecorino Romano cheese, chopped fresh flat-leaf parsley, and grated lemon rind in a small bowl. Bring water and Broccolini to a boil in a large ovenproof skillet.
Cover and cook 6 minutes. Uncover and cook 30 seconds. Remove Broccolini from pan. Add olive oil and minced garlic to pan; sauté 30 seconds. Stir in Broccolini and kosher salt. Sprinkle panko mixture evenly over pan. Broil 2 minutes or until lightly browned.
