In a small bowl, combine chia seeds, natural sweetener, and lemon or lime juice. Stir vigorously for 30 seconds until well-coated, then let sit for 5 minutes to thicken.

Wash and hull fresh strawberries, then pulse them in a food processor until desired texture is reached, about 20-30 seconds.

Add the chia mixture to the processed strawberries and blend for another 15-20 seconds until fully combined.

Transfer the mixture to a mason jar or airtight container and refrigerate for about 30 minutes to thicken further.

Serve on toast, pancakes, or yogurt. Store any leftovers in the refrigerator for up to one week.
