I make similar fish tacos, but I grill the Tilapia. I use a grill topper over the grill grates to prevent the fish filets from falling through. A grill topper is one of those perforated flat trays designed for grilling small items. Buy one where you buy outdoor grills.
I make my own seasoning from a tablespoon of Ancho powder, a teaspoon of cumin, a teaspoon of
garlic powder and a 1/4 teaspoon of oregano. mix together and put in a shaker, then sprinkle on both sides of the fish fillets. This is enough seasoning mix for two or three batches. (It's good on
grilled chicken too.)
I spray the grill topper lightly with olive oil spray and allow it to heat up before adding the fish fillets.
I garnish the tacos with angel hair shredded cabbage, black beans, a slice of avocado or a dab of guacamole, and a spoon of fresh Pico de Gallo. If you want, add a bit of fat-free shredded cheddar.
Sometimes I use low-fat flour tortillas and make a wrap.
