Cut the Quest bar in half, and place each piece in a large silicone muffin cup.
Bake for about 6 minutes, until they puff up.
Meanwhile, press the juice out of the pineapple chunks.
Mix pineapple juice with whey protein powder, and set remaining pineapple aside.
Remove crusts from the oven, and let cool a minute.
Press the quest pieces into the cups, letting the sides come up higher than the centers.
Bake for about 5 minutes more.
Remove crusts from oven, and let cool.
Fill crusts with whey mixture, and top with remaining pineapple.
Enjoy! And store in the refrigerator.
Notes
A note about substitutions: You can use casein instead of whey, but vegan proteins would be a bit chalky or earthy here. Also, be sure to use good pineapple!
