Put a large skillet on at medium heat and swirl just enough olive oil to barely cover the bottom. The sausage is going to add some oil of its own. Lay the sausage out in the skillet and with a small pointed knife poke 3 or 4 holes in the sausages. Then turn them over and poke the other side.
While the sausage is cooking cut up the veggies. Clean and remove the eyes from the potatoes and cut them in half lengthwise then into slices about 3/8" thick. Clean the pepper(s) and cut them in half lengthwise. Pull the seeds and the stem out. Then cut them lengthwise into strips about 3/4" wide then cut the strips into three pieces each. Cut the onions into strips about 1/2" wide. Slice or chop up the garlic.
It should be time to turn the sausages over now. Flip em, then spread the potato slices around the sausages. With your tongs turn the potatoes over a few times as they cook.
When the potatoes are starting to get little brown around the edges push the sausages out to the sides of the pan with the potatoes and add the peppers and onions to the middle. Add some ground black pepper and some dried basil. Turn the peppers and onions over a couple of times as they cook.
When the Peppers and onions are just starting to show signs of getting cooked around the edges mix it all together and turn or flip it all a few times as everything cooks together.
When it's all just about ready spread it all out to the sides of the pan and spread the garlic out in the resulting bare spot.
When the garlic just begins to get translucent stir or flip everything together and serve it up. Don't forget to top it with some freshly grated parmesan, of course.
