All ingredients ready? Let's begin!
In a very large skillet over medium heat, add the olive oil and sliced potatoes.
Sauté the potatoes until they start to turn golden brown, stirring occasionally, for approximately 10 minutes.
Add the sliced peppers, onion, garlic, and oregano to the potatoes.
Continue cooking for about 5 minutes until the onions and garlic are aromatic and begin to soften.
Add the water to the pan. As soon as it boils, lower the heat, cover the pan, and simmer for 10 minutes. Remove the cover and allow the vegetables to continue cooking until the water has evaporated.
Stir in the Calabrian chili paste, if using. Season with salt and pepper to taste. Turn the heat off and stir in the basil and parsley.
Transfer the potatoes and peppers to a serving bowl and serve while warm with your preferred protein or a mixed green salad.
