Add milk and salt to a medium sauce pan.
Bring to a slight boil of medium high heat.
When milk starts to get foamy around the edges, turn heat down to medium and add oats.
Stir continually to prevent boiling over.
Cook until thickened, about 7-8 minutes.
Stir in berries, brown sugar, cinnamon and nutmeg.
Spoon into bowls and top with lemon zest.
