You can re-invent lots of recipes to make them healthier.
Here are some tips:
*use skim milk instead of whole
*use evaporated fat-free milk in place of cream, or skim milk + reduced fat cream cheese
*use Velveeta Lite instead of cheddar cheese
*use low fat soups...check the label, as some those not labeled as reduced fat are still low fat...golden mushroom,for instance
*use ground turkey instead of ground beef, and turkey sausage instead of pork
*replace butter or other fat with olive oil
*use nonstick skillets, that require only 1-2 tbls oil for flavor
*steam vegies in chicken broth to give them flavor without rich sauces
*use lots of fresh herbs, garlic, onions, etc to flavor your food so you won't need so much salt
*use whole grain pastas and breads, brown rice, and fewer potatoes (the starch turns to sugar)
*avoid boxed dinners, which are full of sodium and preservatives
*avoid processed meats (lunchmeat, etc) for the same reason
Hope I gave you some ideas!
