This is one of those recipes you can modify to include whatever vegetables you have on hand, and it's going to be delicious. In my case...well, I used pretty much All The Vegetables: zucchini, summer squash, bell pepper, carrots, peas, mushrooms, onions, and tomatoes. Since my boys love pasta so much, I thought I might as well sneak a ton of veggies into the sauce so they'd eat them along with the tortellini. Success! I'm telling you, that method rarely fails.
