About 3/4 a cup of Amande almond milk yogurt (100-130 calories) and a mix of frozen blueberries/raspberries/mango/whatever strikes my fancy. In the morning, I put the yogurt into a small tupper ware, throw the frozen berries in, and by the time I eat it later in the afternoon, the berries are half thawed, have leaked their juices into the yogurt and still have a little pleasant crunch!
Seriously. The sweetness of the berry juice (they are unsweetened frozen berries... I buy the organic ones even!) is amazing. There is NO NEED to buy those pre-mixed yogurts that have all that added sugar and preservatives in them. Berries are natural sugar and out of this world. Also, the bags I buy have the servings listed as TWO and each serving is 60 calories. I make those bags last me 5 or 6 servings, so this snack is always under 200 calories, which is a perfect pick me up :)
I always forget I've packed this little treat and get so excited when I pull it out of my lunchbox. Mmm!
Also, the plain Amande yogurt (http://amandeyogurt.com/) is SO good. There is something really delicious about it... it doesn't exactly taste like almonds, it's got it's own thing going on.
I don't get paid to rave about things I love, I just want to share them with the world, haha. Give it a try!
