Mix the honey, mustards, and lemon juice together. Place the salmon fillets on a lightly greased shallow baking tin. Brush with the honey glaze. Cover and leave to marinate for 15 minutes.
Preheat the broiler to high and cook the salmon, skin side first for 7-8 minutes, turning after 5 minutes. Brush with marinade 2-3 times during cooking. Sprinkle the top with chopped dill at the end of cooking.
Place the remaining glaze in a small pan and heat until just bubbling. Serve the salmon steaks drizzled with the remaining glaze. Garnish with lemon wedges and serve with peas, if wished.
