Spread cream cheese on one side of the flour tortilla.

Sprinkle blueberries over half of it. Fold other size over and press down lightly.

Spread ½ tablespoon softened butter on one outside of the quesadilla, flip and spread the remaining ½ tablespoon butter on the other outside. Optional: Generously sprinkle cinnamon and sugar over the buttered sides.

Place on a skillet over medium heat and grill each side until golden brown.
