Spinach has gotten a bad rap over the years. What kid hasn't cringed when mom plops a limp and lifeless pile of the green stuff on his plate? No question, it's good for you -- but it feels like you're being punished rather than fed. Not so, if you take it undercover -- or, in this case, under pasta.
Replace nutrition-free white pastas with the whole-wheat variety. Use organic canned tomatoes and sauces to avoid unnecessary sugars and oily additives. Skim milk mozzarella helps you keep the cheese without all the fat. And finally, replace the sausage or hamburger with spinach and you've got a hearty-yet-healthy meal.
