If fresh spinach is unavailable or too much trouble,
10 oz frozen spinach may be substituted for 2 lb fresh.
Trim, wash, and drain spinach. Cut into 1" to 2"
widths. Mix miso, soy sauce, and vinegar; set aside.
Heat wok over high heat. Add almonds and stir-fry
until fragrant and edges turn golden, about 45
seconds. Transfer to plate. Heat oil in wok. Add
spinach and ginger and stir-fry just until tender,
about 3 minutes. Drizzle with bean mixture. Serve
immediately!
