In a shallow bowl, mix together cornmeal and bread crumbs.

Season the fish with taco seasoning, coat in flour, then dip into the beaten egg. Dredge in the cornmeal mixture until well coated.

Ensure that inner pot of Instant Pot Duo Crisp + Air Fryer is dry, then place the air fryer baskets inside the pot. Divide the fish into two batches and place the strips in the basket without overcrowding. Drizzle each batch with ½ tbsp olive oil.

Using the Air Fryer Lid, select Air Fry at 400°F / 204°C for 3 to 5 minutes or until the fish is golden brown and cooked through.

Meanwhile, in a bowl, stir together sour cream, cilantro, canola oil, lime juice, jalapeño, garlic, salt, pepper, oregano, and cumin to make the chimichurri sour cream.

Assemble the fish in warm tortillas with shredded cabbage, chimichurri sour cream and radishes. Serve with lime wedges. Enjoy!
