Use a medium saucepan, mix strawberries (with tops off) with 1 tablespoon of sugar, and lemon juice. Heat over low heat until thickened. Take off the heat, add chia seeds, and let cool before using
Roll the Dough On a lightly floured surface, roll out one dough disk to about 1/8-inch thickness.
Cut Rectangles: Use a sharp knife, pizza cutter, or pastry cutter to cut the dough into a 3x4-inch rectangular shape. Repeat with the second dough disk. You should have an even number of rectangles.
Place half of the rectangles on a parchment-lined baking tray. Spoon about 2-3 tablespoons of the filling onto the center of each rectangle, leaving a small border around the edges.
Brush edges of the filled rectangles with water. Place another rectangle on top, pressing down gently to seal. Crimp with a Fork-Use a fork to crimp the edges for a classic pop tart look.
Poke a few small holes in the top of each pop tart to allow steam to escape during baking. Last, add a little bit of egg wash on top.
Preheat your oven to 350°F (190°C). Bake the pop tarts for 20-25 minutes or until golden brown.
Remove from the oven and let the pop tarts cool completely on a wire rack before glazing.
In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
Drizzle or spread the glaze over top of the pop tarts. Add sprinkles if desired.
Allow the glaze to set for about 10-15 minutes before serving.
