In a medium saucepan, combine rolled oats and water. Bring to a boil, then reduce heat and simmer for 5-7 minutes, stirring occasionally, until oats are tender and have absorbed most of the liquid.
Stir in the mixed berries, chia seeds, and cinnamon. Cook for another 2-3 minutes, or until berries have softened and chia seeds have started to thicken the oatmeal.
Divide the oatmeal into two bowls. Top with chopped almonds and a drizzle of honey or maple syrup, if desired.
