Muesli
1) Mix powdered milk and muesli the stir through a small amount of cold water, then keep stirring in more water (about 200ml in total).
Variations: Add some extra dried fruit or honey. If you want to get fancy and make yogurt overnight then the muesli on fresh yogurt is a nice treat.
Some people pre-pack the muesli and powdered milk into a snaplock bach, so you can add the water into the bag and eat straight from the bag. To save plastic, prepare the muesli in a bowl or cup.
