I use everthing bagel seasoning on my go to chaffles as well. One egg, 1 cup shredded mozz, 2 T seasoning , 1.5 T almond flour, 1 t baking soda.
The real key to crisp is cooking them till the steam is all but stopped. I eat them a lot of ways but with softened cream cheese or sour cream are my favorites. Today with pimiento cheese.
