Prepare the tofu: drain and press the tofu. Cut into cubes.
Make the sauce: in a medium bowl, stir together the ingredients for the sauce until well combined. Set aside.
Cook the broccoli: add a drizzle of oil to a large skillet or wok over medium high heat. Add the broccoli and saute for 3 - 4 minutes, until barely softened. Set aside.
Cook the tofu: heat 1 tablespoon of oil in the pan and then add the tofu and cook 2- 3 minutes on each side, until lightly browned.
Make the stir fry: turn the heat to medium low and pour the sauce over the tofu. Let the sauce bubble (turn up the heat if need be) and thicken for about 1 - 2 minutes. Gently stir in the cooked broccoli.
Serve: serve immediately, optionally over rice or noodles and garnished with green onions and sesame seeds.
