Puree about 1 cup strawberries in food processor along with sweetener and gelatin or ground chia seeds.
If you don't have an Instant Pot, first you should get one. But in the meantime, you can make this strawberry compote on the stovetop too. Put strawberries and strawberry puree in a pot and bring to a boil over medium/high heat and bring to a boil. Boil for 3-5 minutes stirring constantly. You want some of the strawberries to break down and some to remain whole, so don't boil for too long.
