Tilapia may seem like the star ingredient of this recipe, but it's actually the jicama and cabbage slaw that gives these tacos their depth of flavor.
Preheat oven to 475 degrees. Line baking sheet with aluminum foil; brush with oil and set aside. Stack tortillas and wrap in foil. In a large bowl, stir together yogurt, cilantro, lime juice, and hot sauce; season with salt and pepper. Add cabbage and jicama and toss to combine; set aside.
Season fish with salt and pepper. Beat egg in medium bowl. Place bread crumbs in a shallow dish. Dip strips of fish in egg, then bread crumbs, pressing crumbs onto fish to adhere. Arrange fish strips on prepared baking sheet and drizzle with 1 tablespoon oil. Bake until golden brown and opaque throughout, 15 to 18 minutes. After about 6 minutes, place tortillas in the oven to warm.
While fish and tortillas bake, cook beans, cumin, and chili powder in a small saucepan over medium until warmed through, 4 to 6 minutes; season with salt and pepper. Set beans, tortillas, cabbage mixture, and fish on table, and let each diner build his or her own taco.
