In a medium mixing bowl, combine rolled oats, milk, Greek yogurt, chia seeds, honey, cardamom, cinnamon, turmeric, ginger, and salt. Stir gently until well mixed.

Check the consistency of the mixture. If it's too thick, add a splash more milk and stir until creamy.

Cover tightly and refrigerate for at least 6 hours, preferably overnight.

Before serving, stir to combine and adjust consistency with a splash of milk if needed.

Spoon the oats into serving bowls and top with chopped nuts and dried mango.
