Preheat the oven to 425°F (220°C).
Trim and halve the Brussels sprouts, and rinse the chickpeas under cold water to remove excess salt from the can. Pat them dry.
In a bowl, toss the Brussels sprouts and chickpeas with olive oil, salt, pepper, and garlic powder.
Spread the mixture on a baking sheet in a single layer. Roast in the oven for 20-25 minutes until the Brussels sprouts are crispy on the edges and the chickpeas are lightly browned.
While the vegetables roast, season the chicken breast with a pinch of salt and pepper. In a skillet over medium heat, cook the chicken breast for about 5-6 minutes per side or until fully cooked. Once done, dice the chicken into bite-sized pieces.
In a small saucepan, combine honey and balsamic vinegar. Bring to a simmer over medium-low heat, stirring occasionally until it slightly thickens, about 3-4 minutes.
Once the Brussels sprouts and chickpeas are roasted, transfer them to a large bowl. Add the diced chicken breast and drizzle the honey-balsamic glaze over the top.
Gently toss to combine all ingredients, ensuring everything is well coated with the glaze.
Serve warm and enjoy your balanced, nutrient-packed meal.
