Shred the cheese using the finest grater you have. Remove the seeds from the jalapeno and grate it on the same grater. Finely chop the ham and scallion.
Combine all ingredients in a bowl. Mix well.
Pour 1/4 of the batter into a hot waffle iron sprayed with cooking spray (I like using coconut oil or ghee spray for the best flavor). Cook 2-3 minutes, until golden brown and crispy around the edges.
Remove the waffle from the waffle iron - it will continue to crisp as it cools.
Repeat with the remaining batter.
Enjoy these chaffles warm or at room temperature.
Notes
Chaffles reheat best on a baking sheet in the oven, or in a toaster oven (not a pop up style toaster)
