In a large mixing bowl, place the peeled the shrimp. One by one, add in the dry spices (dry
mustard, onion powder, garlic powder, ground cumin, dried thyme, paprika, kosher salt,
cayenne pepper). Mix until all shrimp are evenly coated in seasoning.
Heat a large sauté pan to medium heat. Carefully place the butter in the pan, and spread it
around while it melts. Once the pan is coated evenly in butter, individually place each shrimp
on their side. Cook each shrimp until it turns pink on one side, then flip the shrimp and repeat
this process. Each side should take about 3-4 minutes.
Set up the desired amount of taco shells (hard or soft) off to the side. Transfer the cooked shrimp to the taco shells, and let cool for about 5 minutes. Once cool, add on desired amounts of diced tomatoes, black bean and corn salsa, shredded Muenster, and chopped cilantro.
