Prepare tofu through Step 3 according to Crispy Tofu. Once cubed, lightly pat it dry with a paper towel. (Note: If you do not have time to freeze the tofu, you can skip Step 1.) While the tofu cooks, prepare and chop the other ingredients.
Place the tofu in a separate medium bowl. Top with the 3 tablespoons soy sauce, 1 1/2 teaspoons chili-garlic sauce, 1 1/2 teaspoons sesame oil, and honey. Transfer to a large ziptop bag and sprinkle with 5 tablespoons cornstarch. Tightly seal the bag and shake until the tofu is evenly coated in a gummy white layer.
In a small bowl or large measuring cup, stir together the sauce ingredients: water, soy sauce, hoisin, ginger, chili-garlic sauce, rice vinegar, cornstarch, and sesame oil.
In a large nonstick skillet or wok, heat 2 tablespoons canola oil over medium. Once the oil is shiny and hot, using a slotted spoon, add the tofu to the pan a few pieces at a time, discarding any excess cornstarch. Cook the tofu for 3 to 4 minutes, turning often so that it is golden brown on all sides. Remove from the pan and set aside.
Increase the heat to medium high. Add the remaining tablespoon canola oil and let heat 30 seconds, then add the broccoli and bell pepper. Cook until crisp-tender, about 4 minutes, stirring frequently. Add the chopped green onions and continue for 1 to 2 additional minutes, stirring frequently.
Add the sauce and tofu. Stir to coat the tofu in the sauce and continue cooking, stirring often, for 1 to 2 minutes, until the sauce slightly thickens and the ingredients are warmed through. Taste and add additional chili-garlic sauce if desired. Remove from heat and sprinkle with sesame seeds. Serve hot with prepared rice.
