Line large baking sheet with parchment or silicone liner.

In a small dish, combine seasonings: 1/2 tsp cumin, 1/2 tsp cayenne pepper, 1 tsp salt and 1/4 tsp black pepper and evenly sprinkle seasoning mix over both sides of tilapia.

Lightly drizzle fish with olive oil and dot each piece with butter.

Bake at 375 for 20-25 min.

To brown edges, broil for 3-5 minutes at the end if desired.

Combine all Taco sauce ingredients in a medium bowl and whisk until well blended.

To serve the tacos, quickly toast the corn tortillas on a large dry skillet or griddle over medium/high heat.

To assemble: start with pieces of fish then add remaining ingredients finishing with a generous sprinkle of cotija cheese and finally that awesome taco sauce! Serve with a fresh lime wedge to squeeze over tacos.
