Slice the strawberries into slices. Place one strawberry, sliced, into each mason jar.
Take 3/4 cup of raspberries and 3/4 cup blueberries and divide them equally among the jars.
Spoon more yogurt on top.
Top with the remaining strawberries, blueberries, and raspberries.
Spoon 1/4 cup granola on each yogurt parfait.
Notes
You can put some granola during the first layer but it will get soggy fast. If you want to make up a few days worth of yogurt parfaits, you can store them in the fridge. If you do that I suggest you hold off and put the granola on top right before you are ready to eat.
