Toast almonds in frying pan over low heat – or in a 350° oven until golden brown. Set aside.
Steam broccolini over water (or boil in salted water) until just tender.
Melt butter in large skillet over medium-high heat; 3-4 minutes until medium brown. Add juice and cook 10 seconds. Remove from heat; stir in peel and salt. Add broccolini and toss; transfer to platter and sprinkle with almonds.
