Start by prepping the potatoes. I like to microwave the potatoes for about 3 minutes to start cooking them and speed up the process.
In a large stainless steel or cast-iron skillet, add olive oil. Add the baby potatoes to the pan. Sauté until they start to brown and are completely cooked through, stirring regularly. The process takes me about 10 minutes, may take up to 15 minutes. Transfer potatoes to a plate and set aside.
In the same skillet, add the sausage, onion and peppers. Cook, stirring occasionally, for another 10 minutes until veggies soften. add garlic and stir for one minutes. Add the reserved potatoes back to the skillet. Finally, add the stock and stir everything together. Allow the mixture to cook until the stock thickens slightly, about 5 minutes. Stir to coat the sausage and vegetables with stock.
Add additional salt and pepper to taste. Serve immediately.
