Given the record-breaking heat yesterday, it turns out I was correct in wishing for more summer days. A cool, summer, refreshing treat seems in order. Also, my sister is doing this 8-weeks-to-a-better-you challenge, so I thought I'd give her something that is sweet, but completely natural and healthy.
2 cups frozen berries (strawberries, raspberries, blueberries, boysenberries are all great)
1 cup plain yogurt
1 Tablespoon lemon juice
In a blender, mix all ingredients until smooth (or slightly chunky, if you prefer). Given the absence of liquid, this will likely require the use of a rubber spatula to scrape the sides and multiple pulses of the blender, but be patient, it will pay off.
If you're really having a hard time getting your ingredients to blend, add a little bit of water or milk.
