Pre-heat the oven to 375º.
Line a baking sheet with aluminum foil and place the 7 tilapia fillets onto a pan. Be careful not to crowd the pan.
Combine spices in a small dish. Sprinkle seasonings over tilapia fillets, season with salt and pepper.
Place the fish into the oven for 25 minutes. Poke fish with a fork to see if it’s white and flaky. It might need 5 more minutes.
Remove the fish from the oven and sprinkle with lime zest, then place filets aside in large glass dish.
Heat a large skillet to medium high with a drizzle of olive oil, corn, red onion and red bell pepper. Sear for 1-2 minutes without stirring. Stir and cook another few minutes until vegetables are tender and caramelized.
Add drained and rinsed black beans and heat for 1 minute.
