To make the waffles: In a large bowl, whisk together the flour, salt, baking powder, baking soda, brown sugar, and cinnamon. Slowly whisk in 1/2 of the milk a little at a time until a thick batter forms (use more milk if needed). Make sure not to over-mix the batter.
Lightly grease the waffle maker with non-stick spray. Cook the waffle batter in the waffle maker according to the directions for the waffle maker.
In a non-stick pan over medium heat brown the chicken sausage on both sides.
In a saucepan over medium heat, bring the Nutella and remaining milk to a simmer while stirring until the Nutella melts and you have a smooth consistency.
Top the waffles with powdered sugar, drizzle with warm Nutella. Serve with banana and chicken sausage.
Notes
Pro Tip - If you do not have a waffle maker substitute store bought waffles.
