Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
Press the tofu for at least 15 minutes to remove excess moisture. Cut the tofu into bite-sized cubes.
In a bowl, toss the tofu cubes with cornstarch until evenly coated.
Spread the tofu onto the prepared baking sheet and roast in the oven for 25-30 minutes, flipping halfway through, until the edges become crispy.
While the tofu roasts, cut the broccoli into florets and slice the red bell pepper into strips. Toss the vegetables with a drizzle of sesame oil, salt, and pepper. Spread them on another baking sheet.
Roast the vegetables in the oven for 20 minutes, or until tender and slightly charred.
In a small bowl, combine low sodium soy sauce, minced garlic, grated ginger, and sesame seeds to create the dipping sauce.
Once the tofu is crispy and vegetables are roasted, plate them together. Drizzle extra sauce over the tofu if desired.
Serve warm and enjoy your nutritious Crispy Sesame Tofu with Roasted Broccoli and Bell Peppers.
