Preheat oven to 375 degrees F. Lightly spray a non-stick baking sheet with oil or use a silicone mat.

In a medium bowl, stir together the 1 TBS soy sauce, red pepper flakes, 3 TBS honey, oyster sauce, salt, pepper, rice wine vinegar, and oil. Cut tofu into ½-inch cubes. Gently add/stir tofu cubes into sauce. Cover, and marinate at least 15 minutes.

Place the tofu on the baking sheet in a single layer (reserve marinade). Spray tops with olive oil (I use the Misto) and bake in a preheated oven for 20 minutes. Turn tofu, and bake until the tofu turns golden brown, about 20 minutes more or until develops a nice crisp crust.

Add additional soy sauce and honey ( 1 TBS each) to the marinade bowl. Add corn starch; whisk to combine.

In a large skillet over medium high heat, add the marinade. Place the tofu cubes into the skillet as well, and stir to coat. Bring the sauce up to a quick boil, then reduce heat to a low simmer. After a few minutes the sauce will thicken; stir to coat tofu. Sprinkle with sesame seeds and green onions and serve immediately.
