To make biscuits, mix all ingredients together in a bowl.
Form into balls (as many/little as you want, I made 6).
Bake at 375 for about 20 minutes or until firm.
To assemble sandwich, take biscuit and cut in half.
Layer on scrambled eggs, top with bacon and arugula.
NOTES
Other great additions to the breakfast sandwich would be avocado, slices of cheese, sausage patties, ham, bell peppers, etc.
The baking powder is optional.
If you use it, the biscuits will be fluffier and get a little bigger
