Place coleslaw mix and onion in a serving bowl and stir to combine. Pour salad dressing into another bowl and stir cumin into it. Pour salad dressing over slaw, tossing to coat it well. Fold in avocado cubes and season with Creole seasoning or salt and pepper to taste. Wipe rim of bowl clean with a paper towel and sprinkle cilantro on top of slaw. Serve slaw at once, or cover bowl with plastic wrap and refrigerate it for up to 24 hours.
