Hearty, crisp potato hash with smoked sausage, peppers, and onions.
Heat oil in a cast-iron skillet over medium-high heat. Add the potatoes, season with seasoning salt and pepper, and allow them to get a brown crust on one side before stirring. Continue to brown the potatoes until they have a brown crust on at least two sides. When the potatoes are browned and crisp, push them to one side of the pan and add the smoked sausage, getting a nice browning on the sausage as well.
Meanwhile, heat oil in another skillet over medium-high heat. Add the peppers and red onion, and stirring often, cook until the vegetables are tender and begin to brown.
Add the cooked peppers and onions to the cast iron skillet with the potatoes and sausage and toss to combine. Taste for seasoning and add more salt and pepper if needed. Serve promptly, preferably with ketchup and/or hot sauce on the side.
