Preheat the oven to 400°F (200°C). Line a baking sheet with foil or parchment and lightly spray with olive oil.
Season the chicken tenders with 3/4 teaspoon kosher salt, rubbing it evenly over the pieces.
Place the flour on a shallow plate. In a bowl, beat the egg until smooth. On a second shallow plate, combine the crushed tortilla chips, remaining 1/4 teaspoon salt, garlic powder, cumin, and a pinch of black pepper.
Working one at a time, lightly dredge each tender in flour, shake off excess, dip into the beaten egg, then press into the tortilla chip mixture to coat completely.
Arrange the coated tenders on the prepared baking sheet in a single layer. Lightly spray the tops with olive oil.
Bake for about 8 to 10 minutes per side, flipping once, until the chicken is cooked through and the coating is golden and crisp (about 16–20 minutes total).
Alternatively, to air-fry, spray both sides of the coated tenders with oil and air-fry in a single layer at 400°F (200°C) for 5 to 6 minutes per side, working in batches as needed.
To serve, place two tenders per plate, garnish with chopped cilantro, and serve with a lime wedge and salsa for dipping.
