Step 1: Heat olive oil in a large skillet over medium-high heat. Add the sliced smoked sausage and cook until browned on both sides. Remove sausage from the skillet and set aside.
Step 2: In the same skillet, add the diced potatoes. If the pan is dry, add another tablespoon of oil. Spread the potatoes in a single layer and cook for 8-10 minutes, flipping occasionally, until golden and tender.
Step 3: Add the diced onion and bell peppers to the skillet with the potatoes. Sauté for 5-7 minutes until the vegetables are softened and slightly charred.
Step 4: Stir the browned sausage back into the skillet. Season with garlic powder, smoked paprika, salt, and pepper. Toss well to combine and heat through for 2-3 minutes.
Step 5: Remove from heat, garnish with fresh parsley, and serve your smoked sausage and potatoes skillet immediately.
