Preheat oven to 400°F and line a large sheet pan with parchment paper.
Peel and dice the sweet potato and carrots into uniform 1/2-inch pieces.
Cut the chicken breast into bite-sized 1-inch cubes.
In a small bowl, whisk together the tamari, lime juice, honey, grated ginger, minced garlic, and toasted sesame oil to create the zesty glaze.
Place the sweet potatoes and carrots on the sheet pan, drizzle with olive oil, salt, and pepper, and toss to coat.
Roast the vegetables for 10 minutes.
Remove the pan, add the chicken cubes, and pour the zesty glaze over everything, tossing well to ensure even coverage.
Return the pan to the oven and roast for another 12-15 minutes until the chicken is cooked through and the vegetables are tender and slightly charred.
Serve the roasted chicken and vegetables over the warm jasmine rice.
Garnish with sliced green onions and sesame seeds for a fresh, crunchy finish.
