Add water and salt to medium/large saucepan and bring to boil.

Add steel cut oats to boiling water, reduce heat, cover (vented; I put the kids in at an angle so some heat can escape) & simmer approx. 30-40 minutes until desired consistency is reached.

Pour cooked oats into blender, add sliced apples, banana & cinnamon. Blend on high until smooth.

Serve. Makes enough to fill two pint-size mason jars.
