Preheat the oven to 425°F.
In a bowl, whisk together the light coconut milk, lime juice, minced garlic, grated ginger, salt, and pepper.
Place the chicken breast in a shallow dish and pour half of the coconut mixture over it. Let it marinate for at least 15 minutes.
Meanwhile, chop the red bell pepper, zucchini, and red onion into bite-sized pieces. Toss with a drizzle of coconut milk mixture, salt, and pepper.
Arrange the vegetables on a baking sheet lined with parchment paper and roast in the oven for about 20 minutes until they become tender and slightly caramelized.
While the vegetables roast, heat a skillet over medium-high heat. Sear the marinated chicken breast for 2-3 minutes on each side until golden.
Pour the remaining coconut mixture over the chicken, reduce the heat to medium-low, and let it simmer for another 8-10 minutes until the chicken is cooked through.
Serve the coconut cream chicken alongside the roasted vegetables, drizzling any extra pan juices over the top.
