Step 1: Prepare the batter
In a medium Dutch oven, heat 3 inches of vegetable oil to 350 degrees. In a medium bowl, combine rice flour, cornstarch, baking powder, and 1 tsp. Good On You Vegan Chicken Salt. Slowly whisk in beer to create a batter and set aside. In a small bowl, combine Maple Sugar and remaining 1 1/2 tsp. Good On You Vegan Chicken Salt and set aside.
Step 2: Fry
Dip cauliflower pieces into batter to coat. Fry for 2 to 3 min. or until deep golden brown. Remove from fryer and set on a wire rack. Coat in Maple Sugar mixture.
Step 3: Assemble
Separate Hawaiian rolls and cut in half like a burger bun. Heat 4 halves at a time in a waffle iron until golden brown and crispy, about 2 min. Fill waffle buns with fried cauliflower, spinach, and pepper jack cheese. Serve warm.
