Cook bacon in a skillet over medium heat until cooked through. Transfer to paper towel lined plate. Reserve pan drippings but remove from heat so that it doesn't burn while you prepare the pancakes.
Combine bacon, mashed potatoes, eggs, green onions and romano cheese. Mix well. Form into 4 - 6 hamburger sized patties.
Combine panko, garlic powder and kosher salt on a plate. Press potato pancakes into the panko mixture.
Return the bacon drippings to medium heat. Once hot, place pancakes into drippings. Cook until browned on both sides and warmed through. About 3 minutes each side. Serve.
