Pumpkin, for instance, is "so good-for-you, you should eat it every day". Not so with pie dough & sugar! But:
Add 1/5 can of pumpkin (about 3 oz.) to one standard sized jar of spaghetti sauce. Or add pumpkin to your homemade recipe. It will thicken the sauce and take away that acidity that many people add sugar to counteract.
