Whisk the pumpkin, milk, maple syrup, pumpkin pie spice, vanilla and salt until completely smooth.
Whisk in the chia seeds.
Let it sit 10 minutes, then whisk again to break up any clumps.
Cover and refrigerate at least 4 hours or overnight, until thick and spoonable.
Stir, taste and add more maple if you like. Layer the pudding with Greek yogurt in two jars.
Top with granola, pecans and pumpkin seeds just before eating.
Notes
Smooth texture: blend the pudding after it sets for a mousse-like texture.Storage: keeps 4 days in the fridge without toppings. Add granola just before eating so it stays crunchy.
