Full Flavor

The other day while in line at Subway I noticed they had things broken down nicely for you to make healthy decisions. For sauces it read low fat then listed all the low fat options then below that it read full flavor. That's right full fat= full flavor. I had to laugh. Personally I really enjoy Subways low fat options (not sure how truly healthy they are) their sweet onion sauce is yummy! But why is it that low fat/low cal or healthy options for that matter are just never as good? Does anyone have any good low fat but FULL flavor recipes? We are trying to eat healthier around here, but I love me some full flavor!
