Drain the liquid from the tuna can and add the tun to a medium size mixing bowl. Shred any large chunks with a fork.
Shred the cheese and carrots. Add to the mixing bowl along with the peas and onion.
Stir in the mayo, apple cider vinegar, and honey.
Stir in the salt and cayenne. Taste and add more salt if needed.
Notes
I prefer to use solid white tuna in water, but you can use any variety of canned tuna that you prefer. Less is more with the red onion, so the 1/4 cup can be a scant 1/4 cup or even 3 tablespoons. I typically use about 1/4 of a red onion when preparing this.
