Juice the oranges by squeezing the juice from three mandarin oranges, yielding about three tablespoons of fresh juice.

In a mason jar or a sealable container, mix the freshly squeezed orange juice, light coconut milk, chia seeds, maple syrup, and vanilla extract until thoroughly blended.

Let the mixture sit for about five minutes at room temperature to allow the chia seeds to swell.

Seal the container tightly and refrigerate for a minimum of two hours, preferably overnight.

Prepare desired toppings, slicing fresh mandarin oranges and zesting an additional orange.

Once thickened, scoop the pudding into bowls and top generously with Greek yogurt, mandarin slices, orange zest, and coconut flakes.
