Ideally, you can cook all three of the following at the same time, but you can cook the pasta and sausage first, and then cook the veggies before combining.
- Cutting into smaller pieces and sautéing in a little olive oil until done
- Cook according to package (generally they have you steam sausages with a little water on the bottom of the pan until done).
- Once cooked, slice nicely into even pieces. The sausage will end up much neater looking this way, but either will taste fine.
