Prepare the chia pudding by combining the chia seeds, Greek yogurt, maple syrup, vanilla, cinnamon, and cardamom in a bowl or jar. Stir well and let sit for at least 30 minutes, or up to overnight in the refrigerator, to thicken.
When ready to serve, slice the bananas and top the chia pudding with the banana slices, additional pecans, a sprinkle of cinnamon, and a drizzle of date syrup (optional).
