Strawberry and banana is my favorite combination for a smoothie. I tried replacing apple for banana the other day and still loved it. This is not a rare combo. It is perfect for a healthy breakfast or for hunger pangs at 4 PM, which keeps you satisfied and going until dinner.
Strawberries - 5 or 6, hulled
Apple - 1/2 of a medium sized, peeled and chopped
Milk - 2/3 cup
