Sauce: add the teriyaki sauce, Chinese cooking wine, dark soy sauce and brown sugar to a glass jug and whisk to combine then set aside.
Cook tofu: place a large saute pan or wok on the stove top, turn the heat to high and add the peanut oil. Then add the tofu pieces and sprinkle the salt and pepper in. Pan fry the tofu until the edges of each pieces are browned and crispy (5-6 minutes). Once cooked use a slotted spoon to transfer the cooked tofu to a paper towel lined bowl.
Garlic and ginger: without rinsing or cleaning the pan we cooked the tofu in add the garlic and minced ginger. Stir and allow these to lightly fry for 1 minute.
Vegetables: next add the snow peas, capsicum, mushrooms and green onions to the pan. Cook these for 3-4 minutes.
Noodles: read and follow the instructions on the packet to cook the noodles. Then use a colander over the sink to drain them and discard the water.
Combine: add the cooked noodles to the pan with the cooked vegetables. Then add in the cooked tofu. Pour the sauce in over the top of the noodles, reduce the heat to medium-high and then use tongs to toss and combine. Allow the dish to fully heat through.
Serve: sprinkle the toasted sesame seeds and some thinly sliced green onions over the top of the dish for serving. Provide bowls and chopsticks.
