01 - In a medium mixing bowl or a large jar, add rolled oats, milk, yogurt, honey or maple syrup, ground cardamom, vanilla extract, and salt. Stir thoroughly until fully combined.
02 - Gently fold in diced mango, raisins or chopped dates, and half of the sliced almonds or pistachios. Mix just until evenly distributed.
03 - Cover the container securely and refrigerate for at least 8 hours or overnight to allow the oats to absorb the flavors and liquid.
04 - In the morning, stir the oats well. If a looser texture is desired, mix in additional milk to achieve preferred consistency.
05 - Top the soaked oats with the reserved sliced almonds or pistachios and extra mango if desired. Serve chilled.
