Instead of
Mayonnaise on your sandwich
Try hummus. It's made from blended chickpeas (a member of the legume family) and is available in many varieties including garlic and artichoke.  Depending on the brand you buy, mayonnaise can be all natural - it's basically oil, eggs, and vinegar, but oil and eggs can be high in fat and may not always be the best choice.  Hummus will give you new dimensions of flavor while providing nutritional benefit!

Instead of
Syrup on your pancakes
Try a fruit topping!  Pancakes are fun to eat, but they definitely need a little something on top.  Most of us reach for the butter and maple syrup because that's all we know.  Try mashing a banana and spreading a thin layer on top.  Applesauce also works great, or try blended blueberries, crushed raspberries or strawberries.  Heck, any berry will take the cake.  Your pancake will reach new levels of tasty.  If you can, process the berries and leave them to release their natural juices in the fridge.  Yum!

Instead of
Ice Cream or Sorbet
Try frozen grapes!  They're a little weird at first, but once you get used to it you can convince yourself you're eating fruit sorbet.  You'll forgo added sugar and preservatives of commercially produced ice cream and sorbet, and you'll get the fiber, pectin and natural sugars from the fruit.  Eventually, you will see what a delight frozen grapes can be.
