Preheat your oven to 400°F for the asparagus.
In a small bowl, combine lemon juice, minced garlic, salt, and pepper to make a marinade.
Pound the chicken breast to an even thickness, then marinate it in the lemon-garlic mixture for about 15 minutes.
Lightly beat the egg white in a shallow dish. In another shallow plate, add almond flour seasoned with a pinch of salt and pepper.
Dip the chicken first in the egg white, then dredge it in the almond flour until well coated.
Heat a non-stick skillet over medium heat and lightly spray with cooking spray or a minimal amount of olive oil. Cook the chicken for about 4-5 minutes per side until golden and crispy, ensuring it is cooked through.
Meanwhile, toss the asparagus with olive oil, salt, and pepper, and roast them in the preheated oven for about 10 minutes until tender.
Plate the crispy chicken alongside the roasted asparagus. Serve immediately and enjoy the bright flavors of lemon and garlic with a satisfying crunch.
