In a mixing bowl, whisk together honey, lime juice, chili powder, cumin, salt, and pepper until well combined. Coat the chicken breasts thoroughly and marinate for at least 30 minutes.

While the chicken marinates, bring a medium pot of water to a boil and add your uncooked rice. Cook until tender, about 15-20 minutes, then drain and set aside.

Heat your grill or skillet over medium heat. Cook the marinated chicken for 6-7 minutes per side until cooked through. Let it rest for a few minutes before slicing.

In a large mixing bowl, combine the cooked rice, diced avocado, chopped cilantro, and sour cream, folding gently to keep the avocado chunky.

Assemble by placing a scoop of avocado rice on each plate, layer with sliced chicken, and serve immediately.
