Keep warm and covered until stir-fry is done.
Place tofu in a strainer with a weighted bowl (or tofu press) to release some liquid from the tofu. Place the arame in a measure cup and cover with 1 cup water.
Prep the ingredients: chop shallot, dice red pepper, slice carrot diagonally, trim ends of mushroom and cut into bite-size pieces, slice bok choy crosswise, and slice green onions.
Heat 1 tablespoon olive oil in a non-stick pan (or wok). Cook the shallots for 2 minutes: add the red pepper and carrots and cook for 5 minutes.
Add the mushrooms, bok choy and green onions and cook an additional 7 - 8 minutes. Remove from the pan and place in a covered bowl to keep warm.
Strain and rinse arame well.
Heat 1 tablespoon olive oil In the same pan, and sear the tofu on all sides. Add the shoyu, mirin, ginger, and vegetable broth. Heat thru.
