Make the marinade by whisking together the marinade ingredients (see recipe context) until combined, then pour over the 4 salmon fillets in a shallow dish.
Cover and refrigerate the salmon, flipping once, and marinate for 4–6 hours.
While the salmon marinates, prepare the strawberry salsa by mixing the salsa ingredients together, then chill for at least 1 hour to let flavors meld.
Preheat the oven to 450°F (230°C). Place the marinated salmon on a grill pan or in a baking dish, spacing the fillets apart.
Bake the salmon for about 14 minutes, or until it reaches your desired doneness; total cook time is about 20 minutes including oven preheating and resting.
Remove the salmon from the oven and serve immediately topped with the chilled strawberry salsa.
