Preheat your oven to 400F
In a medium bowl stir together 2 cups of the flour, the yeast, cane sugar, and salt. Stir in 1 cup warm water until combined. Move the dough onto a floured surface. Knead it until the dough is smooth, adding more flour as needed. Place back in the bowl, covered, and let it rest in a warm area for at least 10 minutes.
Once the dough has rested, split it into three equal parts. Then roll it out into 3 circular 'pizzas' on a floured surface, using a floured covered rolling pin or empty wine bottle.
Make your cashew cheese by combining your 1/2 cup cashews, 1/4 cup of water, 1 tsp of lemon juice, 1 tsp of garlic powder, and 1/2 tsp of sea salt in a high-speed blender or food processor. Blend until smooth.
Prepare your veggies by chopping your red onion, bell pepper and mushroom into small pieces.
On half of the circular rolled out dough pieces, add a few spoonfuls of tomato sauce, followed by your chopped vegetables and approximately 2 tsps of cashew cream. Carefully fold the other side of the dough over the filling and seal with a fork.
Add calzones to a parchment paper-lined baking sheet, and bake for 20 minutes until firm. Enjoy reheated in the microwave dipped in more marinara sauce or cold!
