Hot Pink Watermelon Smoothie

I doubt this is proper food combining, but it's a great way to use leftover watermelon and it makes a fun treat.

1 to 1-1/2 c. frozen strawberries
2 to 2-1/2 c. chopped watermelon
2 whole oranges, peeled
1 freshly squeezed lime

Toss it in a blendtec or vitamix and blend it up. May need to add extra water and/or ice.
