Cherry, Banana, & Mango with a Ginger Cookie
I often make dairy-free ice "cream" in my classes and as dessert for friends who can't believe how great it tastes. Up until recently, I had been making the soft serve yummy in everything from a food processor to a blender to a masticating juicer until someone in a class told me about the Yonanas machine made by DOLE. Using simply frozen fruit, sometimes mixed with cinnamon, cocoa and dried fruits or nuts you can make this delicious treat at home and eat it for breakfast, even!
The Yonanas arrives by surprise!

This machine is very simple, easy to clean and only costs about $50 compared to my juicer which was $300 and my Vitamix (you know they are expensive)!

You just put the frozen fruit through the chute and out comes your guilt-free frozen treat. It is best to allow the frozen fruit to thaw a tiny bit before placing through the hopper. Eat "as-is" for the healthiest option, or top with your favorite combinations of delights. Swirl flavors together or scoop separately. One 1/2 cup serving has only 100 fat-free calories as opposed to dairy ice cream which has twice as much but with the worry of saturated fat and cholesterol. With the added benefit of potassium, B vitamins, soluble fiber, and a host of other vitamins and antioxidants depending on fruit used, you will be doing yourself a dairy-free favor!

NOTE: If you are concerned about blood sugar levels, use fruits other than pineapple. Most fruits have a lower glycemic index than you might think, with the exception of pineapple, certain melons and dried fruits. Be careful to limit additions such as coconut and tree nuts as they will drive up calories and fat intake.
