Add yeast to warm water and allow to sit and bloom for about 3 minutes.
Meanwhile, chop the toppings: pepperoni, green and red peppers, sundried tomatoes, and remove to a plate. (If you'd like to use olives, chop them as well.)
In a large bowl add flour, salt, and sugar, then mix to even out the mixture. Pour in the yeast and with a fork, mix until just combined.
Add pizza toppings and parmesan cheese and mix together to make a tacky dough.
Cover with a damp paper towel and let rise in the bowl 1 hour. Then remove to fridge and let rise another hour.
Grate the parmesan and mince garlic. Once the dough has risen, roll out onto a floured surface until about ½” thick. Sprinkle mozzarella over the middle and mix in garlic.
Bake for 30-35 minutes until golden brown. Halfway through, spray with cooking spray. Then rest before slicing.
