Before you get started,cut up all the vegetables you are using. You'll want to make them similar in size so they all cook at the same rate.
Heat a large saute pan over medium heat and add in the butter and onions.
Saute until the onions are just translucent, then add in the garlic and let it cook for about 30 seconds.
To the onions and garlic, add in the pasta, water, and salt stir well to incorporate and bring to a low boil.
After the pasta cooks for a minute or two add in the vegetables in the following order, leaving about two minutes between additions: carrots, sugar snap peas, zucchini, sweet peas. The veggies all cook at a slightly different rate, and you want them all to come out perfectly cooked in the end.
Once the pasta is cooked and the vegetables are tender (about 15 minutes in total), add in the remaining ingredients (Parmesan cheese, butter, salt and pepper to taste) and stir them in to form a light primavera sauce.
Serve and enjoy!
Notes
If you find that the pasta isn't all the cooked, but the water is gone, add boiling water about ½ cup at a time. If you have a little extra water when the pasta is cooked through, don't drain it. It will just make for a creamier sauce.
