I refuse to buy "fresh" strawberries when it isn't strawberry season because they are never actually ripe and taste either very tart or very bland. I get my off-season strawberry fix in the form of a smoothie using frozen strawberries!
You'll only need three ingredients:
1 cup frozen whole strawberries (it is okay to go slightly over)
1 1/4 cups vanilla coconut milk, such as So Delicious or Silk
1 TBSP agave
Place all ingredients in your blender. Pulse a few times to break up the strawberries some and then blend on low to medium speed until smooth. If the consistency is too thick try adding more coconut milk no more than a few tablespoons at a time until you get the thickness you prefer. Makes about 16 oz of smoothie, enough for two people or one very thirsty person.
For a treat with less sugar you can reduce or skip the agave but if your berries are tart it will affect the flavor.
NOTES: If you aren't using vanilla coconut milk and opting for plain or unsweetened instead you may need to add extra agave and little bit of vanilla extract.
