Preheat your oven to 400°F. Line a baking sheet with parchment paper and lightly coat with olive oil cooking spray.
For the chicken, season the 4 oz chicken breast with salt and pepper. In a shallow bowl, whisk together the egg. In another bowl, place the almond flour.
Dip the chicken in the egg, then coat thoroughly with almond flour, pressing gently to adhere the coating.
Place the coated chicken breast on the prepared baking sheet and spray lightly with olive oil cooking spray.
Bake the chicken in the preheated oven for 18-20 minutes, or until the internal temperature reaches 165°F and the crust is golden and crispy.
While the chicken is baking, peel and grate the sweet potato. Transfer the grated sweet potato to a bowl and lightly season with salt.
Heat a nonstick skillet over medium heat and use a small amount of olive oil cooking spray. Spread the grated sweet potato evenly in the skillet, pressing down lightly to form a waffle shape.
Cook the sweet potato waffle for about 4-5 minutes on each side until golden and crisp. Adjust heat as necessary to prevent burning.
Plate the crispy almond-crusted chicken alongside the golden sweet potato waffle. Serve warm and enjoy your balanced, protein-rich meal.
