Preheat your oven to 425°F (220°C).
In a small bowl, combine paprika, cayenne pepper, garlic powder, onion powder, salt, and black pepper to create your blackening spice blend.
Lightly coat the chicken breast with a small amount of olive oil and generously rub the spice blend on both sides.
Heat a non-stick skillet over medium-high heat and sear the chicken breast for about 2 minutes on each side until it develops a dark crust.
Transfer the chicken to a baking sheet and finish cooking in the oven for about 10 minutes, or until the internal temperature reaches 165°F.
Meanwhile, toss the mixed bell peppers and zucchini with a drizzle of olive oil, salt, and pepper. Spread them out on another baking sheet and roast in the oven for about 15 minutes until tender and slightly charred.
Prepare the whole wheat pasta according to package instructions, then drain.
Slice the cooked chicken and arrange over a bed of pasta, then top with the roasted vegetables.
Serve warm and enjoy your spicy, nutritious meal.
