Pat the chicken breast dry with a paper towel and season both sides with sea salt and black pepper.
In a small glass bowl, whisk together the honey, tamari, minced garlic, and apple cider vinegar until well combined.
Heat the olive oil in a medium stainless steel or cast-iron skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
While the chicken cooks, steam the broccoli florets in a steamer basket for 4-5 minutes until bright green and tender-crisp.
In a separate small pan, sauté the cauliflower rice over medium heat for 3-4 minutes until softened.
Remove the chicken from the skillet and set aside to rest; reduce the skillet heat to medium-low.
Pour the honey-garlic mixture into the skillet, scraping up any browned bits, and simmer for 1-2 minutes until the sauce thickens into a glossy glaze.
Slice the chicken into strips, return it to the skillet to coat thoroughly in the sauce, and serve over the cauliflower rice and broccoli.
Garnish the dish with sesame seeds before serving.
