First, whisk together all the Thai BBQ sauce in a bowl. Set aside.
Now, take your pressed block of tofu(if you need more info on pressing tofu, check out my TOFU COOKING GUIDE) and cut the block into cubes. Add the tofu cubes to a bowl, then sprinkle the cornstarch and salt on top. Toss to coat the tofu.
Heat the olive oil in a large wok or nonstick skillet on medium high.
Then add the tofu, and brown the tofu on each side for 2-3 minutes, reducing heat as needed. Until the tofu is all brown and crispy. Remove the tofu and set aside.
Then add the broccoli, carrots, mushrooms and green beans. Saute for about 10-15 minutes to cook all the vegetables, season with a few pinches of salt.
Add the tofu back to the skillet, and then pour the Thai BBQ sauce to the skillet.
Toss to coat everything in the BBQ sauce and saute for another 2-3 minutes.
Serve with rice or noodles, topped with soy sauce, chili paste, and chives if desired.
