Preheat your oven to 400°F (200°C).
In a non-stick skillet over medium heat, toast the panko breadcrumbs for 30–60 seconds, stirring frequently, until lightly golden and fragrant. Transfer to a medium bowl, whisk in the salt and Gaby Everyday seasoning, and set aside.
In a separate medium bowl, whisk together the eggs and milk. Set aside.
Line a large baking sheet with an oven-safe wire rack and spray it with nonstick cooking spray.
Working one piece at a time, dip each chicken cube into the egg mixture, allowing any excess to drip off. Then, using tongs, toss the chicken in the breadcrumb mixture until well coated. Place each nugget on the prepared wire rack, leaving about 1 inch of space between pieces.
Generously spray the tops of the chicken nuggets with nonstick olive oil spray. Bake for 15–20 minutes, or until the nuggets are golden and cooked through. Use a meat thermometer to ensure the internal temperature reaches 165°F (74°C).
Serve hot with your favorite dipping sauce, such as BBQ sauce, honey mustard, or ketchup.
Optional Method: For extra crispiness, you can pan-fry the nuggets in a neutral oil over medium heat until golden brown and cooked through.
