Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Trim the ends of the Brussels sprouts and cut them in half, then place them on the prepared baking sheet.
Drizzle the sprouts with olive oil and sprinkle with half of the sea salt, black pepper, and garlic powder, tossing to coat evenly.
Roast the sprouts for 20 to 25 minutes, shaking the pan halfway through, until they are tender and the outer leaves are crispy and golden.
While the sprouts roast, cook the chopped bacon in a large skillet over medium heat until crispy, then remove with a slotted spoon and drain on a paper towel.
Season the chicken breast with the remaining salt, pepper, and garlic powder, then sear in the same skillet for 6 to 7 minutes per side until fully cooked.
Slice the chicken into bite-sized strips and combine in a large bowl with the roasted sprouts and crispy bacon.
Drizzle the balsamic glaze over the mixture and toss gently to ensure every piece is coated before serving warm.
