In a small bowl or jar, whisk together the lime juice, honey, vinegar, oil, cumin, salt and pepper. The dressing may be made up to several days in advance and refrigerated. Stir or shake well before using.
In a large bowl, combine the coleslaw mix, black beans, red pepper, green onions, cilantro, and jalapeño pepper.
Pour the dressing over the cabbage mixture and toss gently to combine.
If time allows, refrigerate the coleslaw for an hour or more before serving to allow the flavors to develop and permeate the cabbage. Just before serving, stir in or top with the pepitas or sunflower seeds and chopped avocado.
