01 - In a medium bowl or jar, combine rolled oats, almond milk, chia seeds, maple syrup, poppy seeds, vanilla extract, lemon zest, lemon juice, and a pinch of salt.
02 - Stir well to fully incorporate all ingredients until evenly distributed.
03 - Cover and refrigerate overnight, or at least 6–8 hours, until thickened and creamy.
04 - Before serving, stir again. If the oats are too thick, add a splash more plant milk to reach your desired consistency.
05 - Divide between two bowls or jars. Top with coconut yogurt, fresh berries, sliced almonds, or extra lemon zest if desired. Serve chilled.
