Savory Cheddar-Mashed Potato Waffles

2 Cups cold or room-temperature mashed potatoes (preferably unseasoned)
1 Cup bleached all-purpose flour or 1/2 Cup potato flour (starch)
1 Cup grated sharp cheddar cheese
2 large scallions, thinly sliced
1/3 Cup Garlic Olive Oil
1 large egg, beaten
1 tsp baking powder
2 tsp Sea Salt (use less salt for pre-seasoned mashed potatoes) or try Smoked Bacon Salt
Ground Black Pepper to taste

Sour cream (optional for serving)

Heat the waffle maker. Meanwhile add all the ingredients to a large bowl including 1/2 of the scallions, and whisk thoroughly.

Grease the hot waffle iron well. Add 1/3 cup of batter to the waffle iron for each waffle. Close lid and cook until golden brown on the inside, about 5 minutes per waffle. Top with a dollop of sour cream, additional scallions, and hot sauce, if desired.

Serves 6-8
