Preheat oven to 400°F and line a baking sheet with parchment paper.
Press the tofu using a tofu press to remove excess liquid. Cut the pressed tofu into small cubes (about 100 pieces).
Spread the tofu cubes evenly on the lined baking sheet and bake for 25 minutes, until puffy and slightly crispy on the edges.
In a medium bowl, whisk together sesame oil, soy sauce, molasses, peanut butter, lime juice, and Sriracha until well incorporated. Set aside.
Once baked, add the tofu to the sauce and let marinate for 5-10 minutes, stirring occasionally.
Heat a large, nonstick skillet over medium heat. Once hot, add the marinated tofu and about 3 tablespoons of the marinade.
Cook for about 5 minutes until browned and caramelized, stirring frequently. Remove from the pan and set aside.
In the same skillet, add the remaining marinade, broccoli, and carrots. Cover and cook for about 4-5 minutes until the carrots are slightly tender, stirring occasionally.
Remove the lid, increase heat to medium-high, and add the red bell peppers. Cook for 1-2 minutes more, stirring frequently, then remove from heat.
Serve the cooked vegetables in a bowl over white rice. Top with the caramelized tofu and garnish with crushed peanuts. Enjoy!
