To prepare the dough, combine the warm water and yeast in a small bowl.
Let stand for 5 minutes until foamy.
Stir in the maple syrup and 1 tablespoon (15 ml / 0.5 fl oz) of olive oil.
In a separate medium bowl, whisk together the white whole wheat flour, cornmeal, and salt.
Pour in the yeast mixture and stir with a wooden spoon until a shaggy dough forms.
Add the all-purpose flour, a little at a time, until the dough comes together.
Turn the dough out onto a lightly floured surface.
Knead for 6 to 8 minutes, adding more all-purpose flour as needed, until you have a moderately stiff, smooth, and elastic dough.
Shape it into a ball.
Place the dough in a lightly greased bowl, turning it once to coat the surface.
Cover and let it rise in a warm place for 30 to 45 minutes, or until nearly doubled in size.
Preheat your oven to 425°F / 220°C.
Grease a large baking sheet. Punch the dough down, turn it out onto a lightly floured surface, and let it rest for 10 minutes.
Roll the rested dough into a 14-inch oblong shape and transfer it to the prepared baking sheet. Prick the dough all over with a fork. Pre-bake for 8 to 10 minutes, or until lightly browned.
Remove the crust from the oven.
Brush the surface with 1 tablespoon (15 ml / 0.5 fl oz) of olive oil and sprinkle with oregano. Evenly distribute the sliced tomatoes, roasted peppers, olives, vegan feta, and vegan Parmesan over the top.
Bake for an additional 5 to 10 minutes, or until the crust is golden and the vegan cheeses are melted and bubbly.
If desired, sprinkle with extra fresh oregano and cracked black pepper before slicing and serving hot.
Don't be afraid to customize!
Add a handful of spinach, some sliced red onion, or a few artichoke hearts for even more Mediterranean flavor.
