Preheat your oven to 400°F (200°C).
Prepare the root vegetables by peeling (if desired) and chopping the carrot, parsnip, and red beet into bite-sized pieces. Toss with a little olive oil, salt, and pepper.
Place the vegetables on a baking sheet and roast in the oven for about 25-30 minutes, or until tender and slightly caramelized, stirring halfway through.
While the vegetables roast, season the chicken breast with salt, pepper, and a minced garlic clove. Roast the chicken on a separate baking tray or alongside the vegetables if space permits, for about 20-25 minutes until fully cooked. Alternatively, pan-sear the chicken until cooked through.
In a small bowl, combine nonfat Greek yogurt, lemon juice, mixed fresh herbs, and a drizzle of olive oil. Stir well and adjust seasoning with salt and pepper.
Assemble the bowl by layering the roasted vegetables and sliced roasted chicken, then drizzle the creamy lemon herb dressing over the top.
Serve warm and enjoy your balanced, nutritious meal!
