Preheat the oven to 400 degrees Fahrenheit (200 degrees Celsius) and line a baking sheet with parchment paper.
Toss the chicken tenderloins in a bowl with lemon juice, salt, and pepper.
Prepare three shallow bowls: one with flour, one with the beaten eggs mixed with minced garlic and lemon zest, and one with panko breadcrumbs mixed with dried oregano.
Dredge each chicken piece in the flour, then the egg mixture, and finally the panko breadcrumbs, pressing firmly to adhere.
Arrange the tenders on the baking sheet and lightly spray with olive oil.
Bake for 15 to 18 minutes, turning once halfway through, until the internal temperature reaches 165 degrees Fahrenheit.
Serve warm with optional lemon wedges.
