Pour the 4 packs of Carnation Breakfast Essentials® into the Greek yogurt and mix them together.
Layer about 2 oz of the yogurt mixture into the bottom of 8 parfait cups or small mason jars.
Add a layer of frozen berries, about 1/4 cup.
Add another layer of the yogurt mixture on top of the fruit, about 2 oz.
Add a second layer of frozen berries, about 1/4 cup.
Top with one-third cup of granola. (If you'll be freezing any of the parfaits, do not add the granola now.)
Set the parfaits in the fridge overnight and enjoy in the morning! Or put them in the freezer, and the night before you want to eat them, add the granola topping and put them in the fridge.
