Try different combinations of fruits and nuts for something different each day.
Scoop 1/2 cup oatmeal into each of 5 mason jars (I used 1/2 pint jars). Add 1/2 cup milk, 1 tablespoon chia seeds, 1 tablespoon maple syrup, and 1/4 teaspoon vanilla to each jar. Stir contents of each jar; cover and refrigerate overnight. Top each jar with 1/2 cup of fruit and 1 tablespoon of nuts.
Calorie count depends on the fruits and nuts you choose.
