Add additional flour if needed to form a soft dough. Turn onto a floured surface; knead for 1-2 minutes or until smooth and elastic.
Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place for 20 minutes.
Punch the dough down; place on a greased 16" pizza pan and pat into a 16" circle.
Combine salad dressing and seasonings, brush evenly over dough, all the way to the edges. Sprinkle with cheeses.
For a fluffier cheese bread, at this point, allow the bread to rest for 15 minutes or so. If you're in a hurry, just skip this rise. (The bread will rise while it bakes, too.)
Preheat the oven to 450*F. Bake for 11 minutes or until golden brown. Slice. Serve warm.
Notes
Shred your own cheese: Pre-shredded cheese has added starch that can prevent smooth melting—freshly grated melts perfectly.
Bake on parchment paper: Makes cleanup easy and helps the bottom brown evenly without sticking.
Customize it: Try adding some red pepper flakes for an extra little kick.
