In a large bowl, combine 1/3 cup pizza sauce, bread crumbs, pepper, onion, egg whites and garlic. Add beef; mix lightly but thoroughly. Shape into 6 oval patties.
In a large nonstick skillet, cook patties over medium heat 4-5 minutes on each side or until a thermometer reads 160°.
Meanwhile, place bread on an ungreased baking sheet. Brush tops with oil; sprinkle with Italian seasoning. Broil 3-4 in. from heat 1-2 minutes or until golden brown.
Place remaining pizza sauce in a microwave-safe bowl. Microwave, covered, on high for 10-20 seconds or until heated through. Place patties on toast; top with sauce and cheese. Freeze option: Place patties on waxed paper-lined baking sheet; wrap and freeze until firm. Remove from pan and transfer to a freezer container; return to freezer. Freeze remaining pizza sauce in an airtight container. To use, cook frozen patties and pizza sauce as directed, increasing time as necessary for a thermometer to read 160° for patties and for sauce to be heated through.
