Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Cut the chicken breast into nugget-sized pieces. In a bowl, combine the chicken pieces with garlic powder, salt, and pepper.
In another bowl, mix the whole wheat bread crumbs with the seasonings. In a separate small bowl, lightly beat the egg whites.
Dip each chicken piece first in the egg whites and then coat evenly with the bread crumbs mixture.
Place the coated chicken nuggets on the prepared baking sheet and bake for 15-20 minutes or until golden and cooked through, flipping once halfway.
Meanwhile, preheat your air fryer to 400°F. Cut the russet potato into thin fry shapes. Toss the fries lightly with a bit of salt and a spray of olive oil.
Air-fry the potato fries for about 15-18 minutes, shaking halfway through, until crispy and golden.
For the garden salad, combine mixed greens, cherry tomatoes, and cucumber slices in a bowl. Drizzle with olive oil and lemon juice, tossing gently to coat.
Plate the baked chicken nuggets alongside the air-fried French fries and garden salad. Enjoy your balanced and delicious lunch!
