Recipe Notes

Canned Tomatoes: Some top brands contain high fructose corn syrup, so be sure to check ingredient labels and choose the healthiest, cleanest ingredient list you can.

Tortellini: We used Rosetto brand in testing this recipe. We typically recommend whole-grain pasta whenever possible, but the whole-wheat tortellini available in our local stores is notably higher in fat, and we always try to balance our preference for whole-grain foods against fat content and other nutritional issues. Choose the healthiest tortellini you can find. There is a definite difference in the fat content of various brands, so read the labels carefully. We encourage you to choose higher-fiber, low-fat, organic or all-natural products whenever it’s feasible.

Parmesan Cheese: To make this pasta recipe truly vegetarian, be sure to select a parmesan cheese made with non-traditional enzyme alternatives from microbes or fermentation, rather than the traditional rennet.
