Korean Beef and Pimpinella Stir-fry

Beef sliced thin for bulgogi is marinated in soy sauce, cooking wine, minced garlic, and black pepper for ten minutes, then spread in a single layer across a hot pan so every piece browns without steaming. Crowding the pan drops the temperature and causes the meat to stew in its own liquid rather than sear. Sliced onion goes in next for two minutes to coax out its sweetness, followed by chamnamul, a Korean wild green with a distinctive herbal fragrance that sits somewhere between celery leaf and parsley. The chamnamul needs only forty seconds in the pan; any longer and the stems lose their snap while the leaves go limp and the aroma dissipates. Sesame oil stirred in after the heat is off wraps every piece in a smooth richness, and whole sesame seeds burst with a small pop of nutty oil when bitten. At 365 calories and 30 grams of protein, this is a nutrient-dense plate where the bright, almost grassy scent of the spring greens keeps the beefy weight from feeling heavy.
