Add all ingredients to a large container with an airtight lid and stir well. Seal and place in the refrigerator overnight (or at least 6 hours). Taste oatmeal for flavor and add more pure maple syrup to taste. Serve with fresh strawberries, a drizzle of coconut milk or almond milk, and slivered almonds.

Add the oats, chia seeds, coconut, maple syrup, coconut milk, and almond milk to a medium-sized pot. Bring to a full boil over medium-high heat, then reduce heat and simmer for 15 to 20 minutes, stirring occasionally, until oatmeal has thickened and the liquid has been absorbed. Remove from heat and stir in vanilla extract. Divide between four bowls and top with strawberries, almonds, and nuts, along with additional almond and/or coconut milk, if desired.
