They are pretty darned delicious, I have to say.
plain Greek yogurt (I used my homemade) (could add sweetener if desired, we didn't find it necessary)
|Jelly happened to be sugar free. Not a necessity|
Break graham crackers into two squares.
Spread a little jelly on one square.
If desired, spread a little nutella on the other graham cracker.
Top with a dollop of Greek yogurt.
Sprinkle a few blueberries on top of the yogurt.
Form a sandwich of the two graham crackers and enjoy!
