Preheat your oven to 425°F.
Cut the bell peppers and zucchini into bite-sized chunks and toss them in a bowl with olive oil, salt, pepper, and minced garlic.
Spread the vegetables evenly on a baking sheet and roast in the oven for about 20 minutes until tender and slightly caramelized.
While the vegetables roast, season the chicken breast with salt, pepper, smoked paprika, and cumin.
Heat a skillet over medium-high heat and sear the chicken breast for 2-3 minutes per side until golden brown.
Lower the heat, cover the chicken, and cook until the internal temperature reaches 165°F, about 6-8 minutes total.
Remove the chicken from the skillet and let it rest for a few minutes.
In a small bowl, mix the nonfat Greek yogurt with a pinch of salt and extra smoked paprika if desired to form a light, creamy sauce.
Slice the chicken breast and plate it alongside the roasted vegetables, then drizzle the creamy yogurt sauce over the top.
Serve immediately and enjoy your flavorful, balanced meal.
