Salmon-Shiitake Rice Bowls

Whisk miso with 1 tablespoon each honey and vinegar in a shallow vessel. Add salmon, turn to coat. Cover and refrigerate. Toss cucumber with 1/2 teaspoon salt; let stand 10 minutes, then drain. Toss with remaining 1 teaspoon honey and 1 tablespoon vinegar.

Melt butter in a saucepan over medium heat. Add mushrooms; season with salt and pepper. Cook, stirring, until golden, about 5 minutes. Stir in rice; cook, stirring, 1 minute. Add 1 3/4 cups water; season. Bring to a boil, then reduce heat to low, cover, and cook 15 minutes.

Remove from heat; add peas and let stand, covered, 10 minutes. Fluff with a fork. Preheat broiler. Scrape marinade off salmon; place on a broiler pan and broil until blackened in places and cooked through, 5 to 6 minutes. Let cool; serve with rice and cucumber.
