I found this recipe (& accidentally modified it) on heavenlyhomemakers my kids think they're getting dessert, but it's really healthy enough to count as breakfast. And easy too!
1 cup milk
1 cup frozen strawberries
1 tsp vanilla
1 Tbsp maple syrup
(the original recipe also called for 1 cup cream, but I missed adding that & it was still good, though that would explain why we ate it w/ a spoon, not a straw LOL).
Put it all in a blender & blend it up, pour into a cup & enjoy!
