Slice block of tofu sideways and lengthwise into 4 or 5 rectangle planks. Sauté each plank in vegetable broth until lightly brown, replenishing vegetable broth as it evaporates and deglazing evaporated broth from the pan as you replenish.
Dry rub each plank with this spice mix until completely coated.
Spread coated tofu slabs on a parchment-lined baking sheet, and bake at 400 degrees for 20 minutes. Allow slabs to cool.
To use in salads: slice slabs into 1/2-inch squares and use with preferred salad dressing.
To use in sandwiches: refrigerate planks until chilled, then place between bread slices and garnish with lettuce, tomatoes, and any condiments you prefer.
