2tablespoonstoasted sesame seeds
2eachscallions, thinly sliced
Instructions
Butterfly heart and remove interior structural muscles (these look like thick threads of muscle. They're edible, but not very attractive, and cook more quickly than uniform slices). Trim exterior fat and slice as thinly as possible, 1/8" or thinner.
Heat oil over medium-high heat until very hot and shimmering, but not smoking. Add onion, ginger, and garlic and sauté while stirring until fragrant.
Add peppers, sugar and a pinch of salt and sauté for about 45 seconds. Add sherry and bring to a boil.
Add greens and sliced heart, soy sauce, and vinegar. Sauté, stirring vigorously, for about 1 minute, just until greens are wilted. Remove from heat.
Finish with sesame oil, sesame seeds, and scallions. Serve with curly noodles or rice.
Notes
For cold-season variations, substitute julienned carrots for the peppers, and cook them longer for about 2 minutes, until almost tender.
