Slice tofu into eight equal pieces. Press the slices of tofu.
In a small mixing bowl, mix panko crumbs with Italian seasoning and garlic salt.
In a separate small mixing bowl, mix together water and flour.
In a frying pan on medium-high heat, pour a thin layer of oil. Allow it to get hot.
For each slice of tofu: dip into the flour/water mixture, then coat heavily in panko. Repeat for all slices.
Lightly fry each slice of tofu for a minute or on each side, until golden-brown and crispy (it gets crispy fast - make sure it doesn't burn!).
Slice baguette in the middle to create two pieces, then slice each piece lengthwise almost all the way through. Coat the insides of each piece with marinara sauce, then sprinkle vegan cheese and sprinkle vegan parmesan, equally covering each piece.
Place in the oven on low broil until cheese is melted (alternatively, you can grill on a frying pan to melt cheese).
Add tofu and create your sandwiches (they're pretty massive, but delicious!) or enjoy open faced.
