Start by prepping your cod by patting it very dry with paper towels, which is key for getting a crispy texture.
Set up a breading station with three bowls. In the first bowl, combine the flour with half of the chili powder, smoked paprika, cumin, garlic powder, salt, and pepper. In the second bowl, beat the egg. In the third bowl, mix the panko breadcrumbs with the remaining spices.
Dredge each piece of cod in the flour, then dip it into the egg, and finally press it into the seasoned panko until fully coated.
Cook the cod using your preferred method. You can pan fry it in a thin layer of oil over medium heat for 3 to 4 minutes per side until golden and cooked through.
You can also air fry it at 400 degrees for 10 to 12 minutes, spraying with oil and flipping halfway through, or bake it at 425 degrees for 12 to 15 minutes on a rack, making sure to spray well with oil. Once cooked, let the cod rest for a couple of minutes and finish with a light sprinkle of salt.
While the fish cooks, make the mango salsa by combining diced mango, finely diced red onion, minced jalapeño if using, lime juice, chopped cilantro, diced avocado, and a pinch of salt. Toss everything together and let it sit so the flavors can meld.
For the sauce, whisk together Greek yogurt, mayo, lime juice, honey, chili powder, garlic powder, and salt until smooth. Taste and adjust the lime juice and salt as needed.
To build your bowls, start with a base of cooked rice such as white, brown, or cilantro lime rice, and add shredded red cabbage. Top with the crispy cod, a generous scoop of mango salsa, and a drizzle of the creamy sauce.
