Roast the Chicken & Sweet Potato: Preheat your oven to 400°F (200°C). Line a baking tray with parchment paper and add the chicken cutlets and cubed sweet potato. Drizzle with olive oil, season with salt and pepper, and toss to coat. Bake for 30–35 minutes, until the chicken is cooked through and the sweet potatoes are golden and tender.
Make the Greek Salad: In a medium bowl, combine the tomato, cucumber, and bell pepper. Season with salt, a drizzle of olive oil, and toss with crumbled feta.
Assemble the Bowls: Slice the roasted chicken and divide it between bowls with the roasted sweet potato, Greek salad, and a generous scoop of tzatziki.
