A good fruit smoothie is going to be gluten free naturally, but I'm posting it anyways just because it's so good. It's great for breakfast or just because you want one. We always keep frozen fruit in the freezer because we have one of those Yonanas appliances (it uses frozen fruit to make "ice cream"); the frozen fruit takes away the need for any ice. I hope you like!
8 oz vanilla almond milk (or soy or regular, I just really really like vanilla almond milk, and it adds it's own flavor)
1 frozen banana, peeled and diced (peel and dice BEFORE you freeze it!)
10 large frozen strawberries
About 1/2 cup frozen blueberries
Add all ingredients to a blender and use the ice crush function to puree the fruit. Once the big chunks are gone, you can which to one of the other blending functions. I go with a high speed function.
If the smoothie is too thick, add more milk or a splash of orange juice. The orange juice really brings the flavors together. Sometimes I add a container of greek yogurt, or a scoop of whey protein. If you use the protein, you want to blend it with the milk first before adding the fruit. You can use any frozen fruit, this is just my personal preference.
