In a small bowl, mix teriyaki sauce, soy sauce, rice wine vinegar, brown sugar, half of the minced garlic and half of the chopped green onions. Marinate the chopped tofu in this mixture for about 30 minutes, longer if you have time but 30 minutes should suffice. While the tofu marinates, you can cook your choice of starch: noodles, rice, quinoa or couscous. You can also start cleaning up to save time after the meal is ready.
Heat extra virgin olive oil on medium heat in a wok.
Add garlic and veggies and sauté covered for a minute or two.
Meanwhile, mix the corn starch in cold water and set aside.
Add marinated tofu to the garlic and veggie mixture and sauté for 2 minutes.
Add the corn starch and cold water mixture and mix well and cook for another minute or two.
