Preheat oven to 350 degrees and lightly grease a 9×13-inch baking dish.
Separate the crescent dough triangles. Divide strawberries, setting aside 1/2 cup for the sauce. Working one at a time, place a spoonful of strawberries at the base of the triangle, then wrap dough around them and pinch edges to seal. Evenly space dumplings in the prepared baking dish
Add butter and remaining strawberries to a medium-sized microwave safe bowl, heat until butter has melted. Using a fork, mash strawberries into a jam-like consistency. Stir in brown sugar, vanilla, cinnamon, and lemon juice. Pour mixture evenly over dumplings.
Pour soda between the dumplings (not over the top).
Bake for 33-36 minutes or until golden in color. Serve warm with ice cream or whipped cream.
