Follow these simple steps to create your Tofu Broccoli Stir-Fry:

1. Prepare the Tofu: Drain the tofu and press it to remove excess moisture. Cut into bite-sized cubes.
2. Marinate the Tofu: In a bowl, mix 1 tablespoon of soy sauce and sesame oil. Add the tofu cubes and let marinate for 10 minutes.
3. Cook the Tofu: In a large skillet or wok, heat a tablespoon of oil over medium-high heat. Add the marinated tofu and cook until golden brown on all sides. Remove from the pan and set aside.
4. Sauté Vegetables: In the same pan, add a bit more oil if needed. Sauté minced garlic and grated ginger for about 30 seconds until fragrant.
5. Add Broccoli and Other Veggies: Toss in the broccoli florets, sliced bell peppers, and carrots. Stir-fry for 5-7 minutes until the veggies are bright and tender-crisp.
6. Combine Tofu and Veggies: Return the cooked tofu to the skillet with the sautéed vegetables.
7. Make the Sauce: In a small bowl, mix the remaining soy sauce and cornstarch if using. Add this mixture to the skillet, stirring well to combine.
8. Cook Together: Stir-fry for another 2-3 minutes until the sauce thickens and coats the tofu and vegetables.
9. Garnish and Serve: Sprinkle chopped green onions and sesame seeds on top before serving.
