In a mixing bowl, combine rolled oats, 1 cup of milk, and ½ cup of Greek yogurt. Add 2 tablespoons of honey or maple syrup, ¼ cup of fresh lime juice, and 1 tablespoon of lime zest into the mix. Stir well for about one minute until smooth.

Carefully pour the mixture into a jar or an airtight container. Leave space at the top for the oats to expand as they soak up the liquid.

Seal the jar tightly and place it in the refrigerator. Let the oats chill and absorb flavors for at least 4 hours, preferably overnight.

Once set, stir the mixture to combine any settled ingredients. Sprinkle 2 tablespoons of graham cracker crumbs on top before serving.

For an extra zesty touch, garnish with lime slices or a dollop of whipped cream. Serve immediately.
