In a mixing bowl, combine the chia seeds, almond milk, maple syrup, vanilla extract, and a pinch of salt.
Cover the bowl with plastic wrap or a lid and refrigerate for at least 4 hours, preferably overnight.
While the pudding sets, prepare your mixed berries. If using strawberries, slice them to match the size of the other berries.
Once the chia pudding has set, give it a good stir to break up any clumps. Taste and add more maple syrup if you like it sweeter. Spoon the pudding into bowls or glasses, topping each with a generous helping of mixed berries. Garnish with mint leaves, a sprinkle of gluten-free granola, or a drizzle of honey if desired
