Add 3/4 cup each thawed cherries and berries and their juices. Blend on low just to combine. Stir in the chia seeds with a spatula.
Divide and pour half the chia pudding into 4, 1-cup serving, jars, or containers. Top each with 1 Tbsp reserved cherries and berries, then pour remaining pudding over top.
Cover each serving and refrigerate 6 hours or overnight for the chia seeds to thicken the pudding.
Top each pudding with coconut, walnuts, pumpkin seeds and or fresh fruit (such as sliced bananas, fresh berries or kiwi) if you like. Pudding will keep refrigerated for 4 days.
