In a large mixing bowl, on medium speed, mash bananas until there are no large lumps. Mix in brown sugar until blended. Add egg, mix until blended.

Add pinch of salt, ground cinnamon, baking soda, and flour, mix until combined. Add cornmeal, mix until fully combined.
In a small bowl, with 1 Tbsp of flour, toss blueberries until they are lightly coated. This will prevent them from sinking to the bottom of the loaf when it is baking. Gently scoop blueberries out of small bowl into the batter with excess flour left in the bowl. Gently fold the blueberries into the batter.
In a loaf pan lightly greased with butter, pour batter into the pan evenly.
Bake at 350 F for approximately 50-60 minutes until toothpick insert comes out slightly damp but not runny in the middle of the loaf. Cool completely or overnight before slicing.
