To prepare dough, weigh or lightly spoon bread flour into dry measuring cups; level with a knife.
Combine 75 ounces (about 1 cup) bread flour, 1 cup warm water, sugar, and yeast in a bowl; let stand for 15 minutes.
Weigh or lightly spoon all-purpose flour into dry measuring cups; level with a knife.
Combine 5 ounces (about 3 cups) all-purpose flour, remaining 75 ounces (about 1 cup) bread flour, and 1 teaspoon salt in a large bowl; make a well in center.
Add yeast mixture, remaining 1 cup warm water, and 2 teaspoons oil to flour mixture; stir well. Turn dough out onto a floured surface. Knead until smooth and elastic (about 10 minutes); add enough of remaining flour, 1 tablespoon at a time, to prevent dough from sticking to hands.
Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85), free from drafts, for 45 minutes or until doubled in size. (Press two fingers into dough. If indentation remains, the dough has risen enough.) Punch dough down; divide dough into 8 equal portions. Cover and let rest 20 minutes.
To prepare topping, combine oregano, cumin, paprika, and 1/2 teaspoon black pepper.
Heat a large skillet over medium-high heat.
Add 1 teaspoon olive oil to pan.
Add onion; saut 3 minutes.
Add 1/2 teaspoon salt, remaining 1/4 teaspoon black pepper, garlic, bay leaf, and tomatoes; bring to a boil. Reduce heat, and simmer for 15 minutes or until thick.
Remove from heat; discard bay leaf.
Preheat oven to 45
Working with 1 dough portion at a time (cover remaining dough to keep from drying), roll each portion into a 6-inch circle on a lightly floured surface; place circle on a baking sheet coated with cooking spray. Repeat procedure with remaining dough portions. Top each crust with 1/4 cup tomato mixture, 1 1/4 ounces cheese, and 1/2 teaspoon oregano mixture.
Bake at 450 for 12 minutes or until crusts are lightly browned.
