The fish nuggets in this tasty taco are baked, not fried, which translates into less fat — without sacrifi cing a crunchy coating. The secret is panko, delicious Japanese bread crumbs that form the super-crisp outer layer on the fish. The salsa, made with frozen peaches, offers a slightly sweet and tangy complement to the fish, along with a healthy dose of vitamin C.
Heat the oven to 450° F. Line a rimmed baking sheet with foil. Place an ovenproof cooling rack on the baking sheet and coat the rack with nonstick cooking spray.
Stir together the water and the beaten eggs. Place the flour, the egg mixture, and the panko in three separate bowls. Season the catfish with salt and pepper, then dredge each piece first in the flour, then the egg, and finally the panko. Place each coated strip on the prepared rack, leaving a 1-inch space between the pieces. Lightly mist the fish with nonstick cooking spray.
Bake the fish until it's lightly browned, 10 to 12 minutes. Meanwhile, in a medium bowl, stir together the salsa ingredients.
Prepare each taco by placing two or three strips of fish in a tortilla. Top with the Peach Salsa, the shredded lettuce, and if you like, low-fat sour cream or mayonnaise.
