In a blender, blend the fresh berries up with maple syrup & vanilla until smooth (or maybe a bit chunky, depending on your jam preferences).
Put the mixture in a saucepan and heat on medium to low for about 3-4 minutes, stir occasionally.
Add chia seeds, simmer while chia seeds start to gel up and the jam starts to thicken. About 5 minutes.
Turn off heat and keep mixing until consistency is perfect.
Store jam in a glass or jar with a lid. When it's cool seal up the container and store in the fridge for about 5-7 days.
