There is no real recipe to this, smoothies are very versatile and you can make them as you wish with whatever ingredients you want.
I cut up a mango, added a banana and a couple splashes of orange juice. Mixed it all up in my Magic Bullet and then added the last of the spinach we had in the refrigerator to get a dose of veggies! :)
Matt came home from work and said "What the heck is that!" I made him try it and he actually liked it. I've purchased those frozen smoothie packs from the grocery store before, but I like this because I know exactly what is in it. No added sugars, preservatives or anything. Just fruit & a little juice.
