From BHG.com. The original recipe suggests using the broccoli-cauliflower-carrot mixed vegetables. I couldn't find that mix so I used 1 cup of a broccoli-cauliflower mix and 1 cup of a carrots-corn-peas-lima bean-green bean mix. If you are using a shelf-stable tortellini (like Barilla) add an extra cup of liquid, either chicken broth or water. If you are using refrigerated or frozen tortellini, the amounts below should be satisfactory but use more if you like.
