Prep the oven or air fryer. Heat the oven to 425°F (220°C) or preheat the air fryer to 390°F (200°C).
Line a sheet pan with parchment and set a wire rack on top if baking. This keeps the chicken crisp.
Set up the coating. In a shallow bowl, mix panko, crushed cornflakes, smoked paprika, garlic powder, onion powder, salt, and pepper. In another bowl, beat the eggs (or pour in buttermilk).
Coat the chicken. Pat chicken dry.
Dip in egg, let excess drip off, then press into the crumb mixture until well coated. Place on the rack or air fryer basket. Lightly mist with oil or drizzle a tiny bit to help browning.
Cook the chicken. Bake 14–18 minutes, flipping once, until golden and cooked through (internal temp 165°F).
Air fry 10–12 minutes, flipping at 7 minutes. Let rest 5 minutes, then slice.
Char the corn (optional but great). If using fresh or thawed corn, toss with a little oil and a pinch of salt. Sauté in a hot skillet 3–4 minutes until lightly charred.
Cool slightly.
Make the dressing. Stir ranch with lime juice for pourable consistency. In a separate small bowl, loosen BBQ sauce with a splash of water if very thick. For a blended version, mix equal parts ranch and BBQ into a BBQ ranch dressing.
Or keep them separate and drizzle both.
Assemble the salad base. In a large bowl, combine lettuce, cabbage, tomatoes, corn, black beans, and red onion. Toss lightly with half the dressing so the greens are just coated.
Add toppings. Fold in cheese and most of the cilantro. Fan the avocado over the top.
Add the sliced crispy chicken. Finish with tortilla strips for crunch.
Drizzle and serve. Spoon over remaining ranch and a zigzag of BBQ sauce. Taste and adjust with a pinch of salt, extra lime, or fresh pepper.
Serve right away for maximum crunch.
