Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Trim the ends off the Brussels sprouts and cut them in half.
In a bowl, toss the Brussels sprouts with 0.25 tablespoons of olive oil, sea salt, and black pepper.
Spread the sprouts on the baking sheet and roast for 20-25 minutes until the outer leaves are charred and the centers are tender.
While the sprouts roast, season the chicken breast with garlic powder and a pinch of salt.
Heat the remaining 0.25 tablespoons of olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until cooked through.
Remove the chicken to rest, then add the prosciutto slices to the same hot skillet for 1-2 minutes until they become brittle and crispy.
In a small ramekin, whisk together the balsamic vinegar and honey to create a glaze.
Dice the rested chicken and crumble the crispy prosciutto.
Toss the roasted sprouts, chicken, and prosciutto together in a bowl and drizzle with the balsamic glaze before serving.
