Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Peel and cube the sweet potato into 1/2-inch pieces and cut the chicken breast into bite-sized chunks.
In a small bowl, whisk together the raw honey, tamari, minced garlic, and extra virgin olive oil to create the glaze.
Place the chicken and sweet potatoes on the sheet pan, drizzle with half of the honey-garlic glaze, and season with sea salt and black pepper.
Toss everything well to coat and spread into a single layer, then roast in the oven for 15 minutes.
Remove the pan from the oven, add the broccolini, and drizzle the remaining glaze over the greens.
Return the pan to the oven and roast for an additional 10-12 minutes until the chicken is cooked through and the sweet potatoes are fork-tender.
Serve immediately while the glaze is warm and sticky.
