Preheat the oven to 425°F.
Peel and cube the sweet potato into bite-sized pieces. Toss the cubes with half a tablespoon of olive oil, salt, and pepper, and spread them on a baking sheet.
Roast the sweet potato cubes for about 25-30 minutes until tender and lightly browned.
While the sweet potato is roasting, chop the broccoli into florets. Toss the broccoli with a little olive oil, salt, and pepper, then add them to the baking sheet during the last 15 minutes of sweet potato roasting.
Heat a skillet over medium-high heat. Pat the turkey breast dry and season with salt, pepper, and your favorite herbs.
Add a small drizzle of olive oil to the skillet and sear the turkey breast for about 3-4 minutes per side, ensuring a golden crust and that it reaches an internal temperature of 165°F.
Prepare the quinoa according to package instructions, or warm up pre-cooked quinoa for about 5 minutes.
Plate the seared turkey breast alongside the roasted sweet potatoes, broccoli, and a serving of quinoa. Serve immediately and enjoy your balanced, nutritious dinner!
