Step 1

In a small bowl combine mango, lime zest & juice, salt and pepper; set aside 10 minutes, then combine with mayonnaise and refrigerate until ready to assemble sandwiches.

Step 2

In a non-stick skillet over medium heat, add a little butter and toast the buns; remove from pan.

Step 3

Sprinkle fillets lightly with blackening seasoning.

Step 4

Over medium heat, add a little more butter to the pan then add fillets. Cook about 3 minutes on first side, then flip. Cook about 1 minute, then reduce heat slightly and cook another 3-4 minutes, depending on thickness of your fillets. (I sometimes lightly cover the pan to allow the fish to steam a bit and retain its moisture). When done, turn off heat and allow the fish to sit in the pan for about a minute before serving.

Step 5

On the bottom bun, layer some arugula, then the fish and onions. Spread Mango Mayo on the top bun layer, then put it all together and serve immediately,
