Add honey and soy into a zip top bag, squish to mix.
Add the fish and seal the zip top.
Turn to coat. Marinate for 30 minutes or up to 2 hours (we marinated for about an hour).
Drain and discard marinade.
Preheat broiler. If you have the option of low or high, choose high.
Line a rimmed baking sheet with foil and coat foil with cooking spray or lightly drizzle oil.
Place fish on foil. Broil 5 to 7 minutes per 1/2-inch thickness of fish, or until fish flakes easily with a fork.
We broiled for about 7 minutes total.
While the fish is broiling, heat the oil in a large skillet over medium-high heat. Add zucchini and onions. Cook about 3 minutes or until just tender; season with salt.
Serve the fish fillets with the zucchini.
Recipe Notes
Note: if using frozen fillets, be sure to allow to defrost before you marinate. It makes a difference.
