01 - In a large nonstick skillet, heat the olive oil and 1 tablespoon butter over medium heat.
02 - Add the diced potatoes and cook, stirring occasionally, for 8-10 minutes until golden and starting to soften.
03 - Add the onion and bell pepper; cook for 4-5 minutes until the vegetables are soft and potatoes are cooked through. Season with salt, pepper, and smoked paprika.
04 - In a medium bowl, whisk together the eggs and milk until combined.
05 - Push the vegetables to one side of the skillet and add the remaining 1 tablespoon butter to the empty side.
06 - Pour the egg mixture into the buttered side of the pan. Allow to set slightly, then gently scramble, gradually mixing in the vegetables as the eggs cook.
07 - When eggs are just set but still creamy, sprinkle the shredded cheese evenly over the scramble.
08 - Cover the skillet for 1-2 minutes to allow the cheese to melt, then gently fold everything together.
09 - Remove from heat, garnish with fresh chives if desired, and serve hot.
