In a small bowl, stir together peach, brown sugar and cinnamon.
Combine almond milk and 1/4 cup water in a small saucepan and bring to a boil over medium-high heat. Stir in oats and salt. Reduce heat to medium-low. Cook, stirring occasionally, until mixture has thickened and oats are tender, about 5 minutes. Remove from heat.
Spoon oatmeal into a bowl, top with peach mixture and spoon yogurt on top. Sprinkle with extra cinnamon, if desired.
