Prepare the slaw: In a large mixing bowl combine the sliced cabbage, shredded carrot, chopped green onion, minced garlic, olive oil, lime juice, and a pinch of sea salt; stir until well coated.
Taste the slaw and adjust seasoning with more sea salt, lime juice, or oil as desired, then refrigerate until ready to serve.
Make the chipotle crema: In a small bowl stir together the chopped chipotle chiles, 2 teaspoons adobo sauce (or to taste), and the sour cream or Greek yogurt until smooth; season with sea salt and refrigerate.
Cook the rice according to package instructions and warm the black beans on the stove or in the microwave.
Shred the rotisserie chicken into bite-sized pieces.
Assemble bowls: Divide cooked brown rice among bowls, top with warmed black beans, shredded chicken, shredded cheese, a scoop of cabbage slaw, and diced avocado.
Finish each bowl with salsa, hot sauce, and a dollop of chipotle crema to taste, then serve immediately.
