Preheat your oven to 400°F and prepare a baking sheet lined with parchment paper or lightly sprayed with cooking spray.
Place the chicken breast between two sheets of plastic wrap and gently pound to an even thickness for uniform cooking.
In a shallow bowl, beat the egg. In another bowl, combine almond flour with a pinch of salt and pepper.
Dip the chicken breast in the egg, ensuring it is fully coated, then dredge in the almond flour mixture, pressing gently to help the coating adhere.
Place the coated chicken breast on the baking sheet. Lightly spray the top with cooking spray to encourage crisping.
Bake the chicken in the preheated oven for 15-18 minutes, or until the internal temperature reaches 165°F and the crust is golden and crispy.
Meanwhile, prepare the sweet potato waffle: either mash 1/2 medium sweet potato and spread it in a preheated waffle iron until lightly crisp on the edges, or slice the sweet potato into thin rounds and crisp them in a pan as a waffle base.
Once cooked, serve the crispy almond-crusted chicken alongside or atop the sweet potato waffle, and enjoy your balanced, flavorful meal.
