Preheat your oven to 425°F. Line a baking sheet with parchment paper.
Press the tofu for at least 10 minutes to remove excess moisture. Cut into cubes.
In a bowl, add the cubed tofu and sprinkle the cornstarch over it. Toss gently to evenly coat the tofu.
Lightly spray the tofu with cooking oil spray.
Place the tofu cubes on one side of the baking sheet and drizzle lightly with cooking oil spray.
On the other side of the baking sheet, spread the broccoli florets evenly. Season them lightly with salt and pepper if desired.
Roast in the oven for 20-25 minutes, flipping the tofu halfway through, until the tofu is crispy and broccoli is tender with slight char edges.
While the tofu and broccoli are roasting, prepare the peanut ginger sauce. In a small bowl, combine peanut butter, grated ginger, minced garlic, and low sodium soy sauce. Whisk until smooth. If the sauce is too thick, add a teaspoon of warm water to adjust the consistency.
Once roasted, transfer the tofu and broccoli to a serving bowl. Drizzle the peanut ginger sauce over the top and gently toss to combine.
Serve warm and enjoy your crispy, flavorful dish!
