Prep the coleslaw. Add the shredded green cabbage, red cabbage, and carrots to a large bowl.
Make the dressing. Combine the mayonnaise, honey, apple cider vinegar, salt, pepper, and celery seeds in a small bowl and whisk together. (If you want the dressing to be sweeter, add more honey.)
Stir it all together. Pour about half of the dressing onto the cabbage and carrots and toss. Slowly add more dressing until you’ve reached your desired slaw-to-dressing ratio.
