Preheat oven to 350F.

In a mixing bowl, combine Saskatoon berries, sugar, flour/cornstarch, lemon zest and lemon juice. Stir until berries are evenly coated.

You can split your dough into 2 to make to medium sized galettes or make one giant galette (which is what I did)

Roll out your dough into a round-ish shape to about 1/4 inch thickness. Add the berry mixture into the centre and add 1 tsp dots of vegan butter across the berry mixture. This will melt and become part of the sauce.

Fold up the edges of the dough to contain all the berries, it'll look rustic and that's the point. Seal up any cracks you see with any pie dough scraps you have (or just tear from the edges you pulled up).

Brush soy milk or aquafaba all along the outsides of the crust and sprinkle with coarse sugar.

Bake for 30 minutes, or until the crust is nice and golden brown. Let cool slightly before serving, and serve with vanilla soy ice cream for extra deliciousness!
