Step 1
Preheat the oven to 425 degrees. Stir together the olive oil, brown sugar, and blackening seasoning (or another seasoning blend). For a simple option, just use chili powder.
Step 2
Cover a baking sheet with foil. Place the salmon on the foil and brush the salmon with the olive oil and spice mixture. Roast for 12-15 minutes until the salmon is cooked through and flaky. The exact cooking time will depend on the thickness of the salmon. Grilling option: Place the salmon on foil or skin-side down on an oiled, preheated grill. Cook over medium-high heat for 10-15 minutes until flaky.
Step 3
While the salmon cooks, make the corn salsa by combining the corn, red onion, poblano pepper, lime juice, cilantro, salt, and pepper. Add mango, pineapple, or avocado if desired.
