To prepare tofu, cut crosswise into 12 slices. Place a large nonstick skillet over medium heat. Add tofu; cook 5 minutes on each side. Remove tofu from pan; cool to room temperature.
Combine the breadcrumbs, Parmesan, marjoram, savory, thyme, and 1/8 teaspoon pepper.

Repeat procedure with remaining flour, tofu, milk mixture, and breadcrumb mixture. Place a nonstick skillet coated with cooking spray over medium heat until hot. Add tofu; sauté 3 minutes on each side.
