Add the chopped strawberries to a saucepan along with water and lemon juice. Heat over medium while stirring occasionally, until strawberries become saucy. Remove from heat.
Add ½ of strawberry mixture to a food processor or blender. Add date paste, and process until smooth and fully incorporated.
Pour the rest of the strawberry mixture into the food processor, and pulse 2-3 times until strawberries are broken up but still have texture.
Pour the strawberry syrup back into the saucepan, and sprinkle chia seeds over the top. Stir to prevent clumping. Allow to sit for about 5 minutes, and then stir well again before pouring into jars to store.
