We've truly moved so far away from healthy foods and home cooking that we need a magazine to tell us how to make something as simple as stuffed shells healthier?
I've been making stuffed shells like this for years (seriously years)! And it's a family recipe.
Making sauce from scratch (for anything) is so simple and takes so few ingredients, and the cook has complete control over what goes into it. I've never understood buying sauce from the store.
For those who don't care for ricotta, or want an even lower fat dish, low fat cottage cheese can be used. Use it in place of, or mixed with ricotta. Flavor will be retained, though the texture will change slightly.
