Preheat the oven to 400°F (200°C). Line a baking sheet with foil or parchment and lightly coat it with olive oil spray.
Season the chicken tenders with 3/4 teaspoon kosher salt and a bit of black pepper.
Place the flour on a shallow plate. Beat the egg in a medium bowl. On another shallow plate, combine crushed tortilla chips, the remaining 1/4 teaspoon kosher salt, garlic powder, and ground cumin.
Dredge each tender first in flour, shaking off excess, then dip in the beaten egg, and press into the tortilla chip mixture to coat evenly.
Arrange the coated tenders on the prepared baking sheet in a single layer. Lightly spray the tops with olive oil spray.
Bake for about 8 to 10 minutes per side (16–20 minutes total), flipping once, until the chicken is cooked through and the coating is crisp.
Alternatively, to air fry: place tenders in a single layer in the air fryer basket (work in batches if needed) and spray both sides lightly with oil. Air fry 5 to 6 minutes per side until cooked through and crisp.
Serve two tenders per plate, garnish with chopped cilantro, and serve with a lime wedge and salsa for dipping.
