Preheat your oven to 450°F and grease a half sheet pan.
In a large bowl whisk together the marinade ingredients.
Cut the vegetables into large bite sized pieces. Toss with marinade and allow to sit for about 10 minutes.
Drain Marinade from vegetables and arrange veggies on the sheet pan.
Cut Italian sausage into about 1″ pieces. Arrange over the top of the vegetables.
Bake for about 20-25 minutes or until the veggies are cooked to your liking and the sausage is cooked through. Grate some Parmesan cheese over the pan and return to oven for just a minute or two to melt.
Serve over pasta or rice if desired.
Notes
Feel free to use whatever vegetables you have on hand or like best. Sometimes I add peppers, or if I don't have mushrooms I just add more zucchini. Mix and match however you would like, but use somewhere between 10-14 cups of vegetables.
