Heat broiler to high with rack set 6-inches from element.
On a large baking sheet, toss peas with oil, ½ teaspoon salt and ¼ teaspoon black pepper. Broil peas until slightly tender and starting to char, 3–6 minutes (see notes below)*
Meanwhile, whisk together honey, 2 teaspoons lime zest, coriander, cayenne, and ¼ teaspoon salt.
Clear four spaces on baking sheet and arrange salmon fillets skin-side down on prepared sheet; pat dry and season with ½ teaspoon salt and ¼ teaspoon black pepper.
Reserve 2 tablespoons of glaze in a separate bowl for serving; spread remaining glaze evenly over salmon fillets.
Broil salmon until mostly opaque but center still looks undercooked, tops are charred, and an instant-read thermometer inserted in the centers registers 120–125ºF (48–52ºC), 10–12 minutes.
Spoon reserved glaze over salmon and sprinkle with scallions. Serve with lime wedges.
