Start by peeling and slicing the medium potatoes into thin rounds. This will help them cook evenly and achieve that perfect golden crisp.
In a large skillet, heat 2 tablespoons of olive oil over medium heat. You want the oil to shimmer but not smoke, which indicates it's ready for the potatoes.
Add the sliced potatoes to the skillet. Sprinkle with salt and pepper to taste. Cook for about 10-12 minutes, stirring occasionally until they are golden brown and tender. If they start to stick, add a little more olive oil.
Once the potatoes are cooked, add the chopped red pepper, green pepper, and red onion to the skillet. Sauté for another 5-7 minutes until the vegetables are softened and fragrant.
Now it’s time to add the sliced kielbasa to the skillet. Cook for an additional 5 minutes, allowing the kielbasa to heat through and get a bit crispy.
With the skillet mixture ready, create two small wells in the mixture. Crack an egg into each well and cover the skillet with a lid. Cook for about 5 minutes or until the eggs are cooked to your desired doneness.
Once the eggs are cooked, sprinkle the shredded mozzarella cheese over the entire skillet. Cover again for another 1-2 minutes until the cheese is melted and bubbly.
Remove the skillet from heat. Top with chopped scallions for a pop of freshness. Serve hot and enjoy the deliciousness of The Ultimate Breakfast Skillet!
