Combine Dry Ingredients: In a large mixing bowl, add the rolled oats, chia seeds, ground cardamom, and salt. Whisk briefly to distribute everything evenly.
Whisk Wet Ingredients: In a separate medium bowl, combine the unsweetened almond milk, fat-free plain Greek yogurt, maple syrup, and vanilla extract. Whisk vigorously until the mixture is completely smooth.
Combine & Fold: Pour the wet mixture over the dry ingredients. Add the chopped fresh strawberries and gently fold with a silicone spatula until no dry pockets of oats remain.
Portion and Chill: Evenly divide the oat mixture among the four jars. Secure the lids and refrigerate for a minimum of 4 hours, or overnight. This allows the oats and chia seeds to soften and absorb the liquid.
Serve: Once chilled, the mixture will be thick and creamy. Stir gently before serving. Garnish with fresh strawberry slices, an extra dollop of yogurt, and toasted almonds, if desired.
