The Rainbow Veggie Tofu Stir-Fry is a delightful festival of colors and flavors on your plate. Crisp vegetables like broccoli, red bell pepper, carrots, and snap peas come together with golden-brown tofu cubes, tossed in a savory sauce blend that's equal parts tangy and spicy. Each bite is an explosion of freshness, with a subtle heat from red pepper flakes.
In a small bowl, combine the soy sauce, hoisin sauce, rice vinegar, sesame oil, and red pepper flakes. Pour over the tofu and vegetables, tossing to coat evenly.
Cook for another 2-3 minutes until the sauce is heated through.
Sprinkle with green onions and sesame seeds before serving.
