In a large pot add the potatoes and salted water. Bring the water to a boiling and cook the penne pasta until they are al dente.
Meanwhile in a large deep skillet heat 1 tablespoon of the olive oil until warm, but not smoking.
Add the sausage to the skillet. Cook on medium high heat until nicely browned and cooked through. About 5 minutes.
Add the tomatoes and cook over medium low heat.
Add the pasta and potatoes to the skillet and add the butter and cook stirring until the pasta is well coated.
Transfer to bowls and serve right the way.
Notes
Pro Tips
Al dente pasta or to the bite is when you remove the pasta from the boiling water a minute or two before it is fully cooked. This will allow you to cook them a minute longer with the sauce and not become too mushy and uneatable.
When adding liquid, even though they are seeded tomatoes, moisture will be added to your hot skillet with the sausage, and that will cause a splatter of hot oil and tomatoes all over your stove. I suggest having a lid and cover to protect you when adding the tomatoes to the sausage.
