Preheat your oven to 400°F.
Pat the chicken breast dry. Season it generously with paprika, garlic powder, salt, and pepper.
In a skillet, heat half of the olive oil over medium-high heat. Sear the chicken on both sides until a golden crust forms, about 2-3 minutes per side.
Transfer the seared chicken to a baking dish and finish cooking in the oven for 10-15 minutes or until the internal temperature reaches 165°F.
While the chicken is baking, prepare the vegetables. Chop the zucchini, red bell pepper, and broccoli into even pieces.
Toss the vegetables with the remaining olive oil, salt, and pepper, then spread them on a baking sheet.
Roast the vegetables in the oven for about 15 minutes until they are tender and slightly charred on the edges.
Plate the chicken alongside the roasted vegetables and serve immediately.
