You can roast ant veggies you'd like, but I must say the 3 I used went so well together.
Ingredients
3 tbsp extra virgin olive oil
3 cups broccoli florets
1 pint grape or cherry tomatoes
1 Vidalia onion, quartered
6-8 oz pasta of your choice
3 tbsp Parmesan cheese
Cherry tomato or pearl size mozzarella balls, optional
Salt and pepper
Directions
Preheat oven to 425 and place veggies in a shallow baking dish or on a cookie sheet. Toss with olive oil. Roast for 30 minutes.
