Begin by heating two tablespoons of olive oil in a large skillet over medium heat. The oil needs to be shimmering but not smoking. This will create a perfect environment for sautéing.

Now, add the sliced smoked sausage to the hot skillet. Let it cook for about 4-5 minutes, stirring occasionally until it starts to brown. This step is crucial because browning the sausage adds depth and flavor.

Add in the thinly sliced onion and bell pepper to the skillet. Stir them well with the sausage. Cook everything together for about 3-4 minutes until the onions become translucent and soft.

Next, toss in the halved or quartered Yukon Gold potatoes. Mix everything gently. The potatoes are the star, so you want them to be well-distributed among the sausage and veggies.

Sprinkle in the garlic powder, smoked paprika, Italian herbs blend, salt, and pepper. Stir everything thoroughly, ensuring that the potatoes are coated with the spices.

Reduce the heat to low, cover the skillet, and allow it to cook for 20-25 minutes. The steam created by the cover helps to cook the potatoes evenly. Stir occasionally to keep things moving.

You’ll know it's ready when the potatoes are fork-tender. Once they reach that stage, sprinkle the freshly grated Parmesan cheese over the top. Cover for another couple of minutes, just until the cheese melts.

Finally, remove the skillet from heat and sprinkle with freshly chopped parsley before serving. This adds a nice splash of color and freshness.
