In a mason jar or airtight container, add oats, chia seeds, protein powder, pudding mix, almond milk, yogurt, and lemon juice.
Stir thoroughly until fully combined, making sure to scrape down the sides to mix in the chia seeds and powder.
Fold in frozen or fresh strawberries.
Seal with a lid and refrigerate overnight (at least 4–6 hours).
Before serving, top with crushed graham crackers or a swirl of strawberry jam, if desired.
Enjoy cold straight from the jar or let it sit at room temperature for a few minutes to soften slightly.
