Cook diced apples in water, brown sugar, and cinnamon in a skillet on medium heat, until apples have slightly softened, and the liquid has reduced slightly in volume (about 5 minutes). Stir occasionally. During the last minute of cooking, add the chopped pecans. Once apples have softened slightly, remove skillet from heat.
Divide rolled oats, vanilla, and chia seeds evenly into two containers (I used canning jars). Divide and add apple mixture evenly (plus any syrup left in skillet) into jars. Fill jars with almond milk, until oat mixture is covered. Stir each jar well, to fully incorporate ingredients.
Place a cover on each jar, and place jars in refrigerator overnight. In morning, serve and enjoy! Unopened jars can be stored in refrigerator for 3-4 days.
