Preheat the oven to 400ºF. On a baking sheet, toss the diced potatoes with about 2 Tbsp of cooking fat, and salt & pepper to taste, and lay them out in a single layer. Bake for 20 to 30 minutes, or until golden brown, tossing halfway through.
Meanwhile, heat a large skillet over medium. Add 2 Tbsp of cooking fat to the pan, and add the steak tips. Cook for a couple of minutes per side, until browned. Remove the steak from the pan, and set it aside on a plate.
Add the bell peppers & onions to the pan, stirring and cooking for about 5 minutes or until soft. Add the garlic and seasonings and stir. Stir in the potatoes and steak, and cook for a couple of minutes until warmed through.
In a small bowl, combine the hot sauce and ranch.
Serve the hash hot with garnish of your choice and a drizzle of spicy ranch. Enjoy!
