Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
Cut the tempeh into cubes or thin strips. In a bowl, toss the tempeh with cornstarch, a pinch of salt, and half of the soy sauce to help with crisping.
Spread the tempeh evenly on the baking sheet and roast in the oven for about 20-25 minutes, turning halfway, until golden and crispy.
While the tempeh roasts, prepare the roasted broccoli. Toss chopped broccoli with a little olive oil, salt, and pepper, and place it on a separate baking sheet. Roast for 15-20 minutes until tender and slightly charred.
In a small bowl, whisk together peanut butter, remaining soy sauce, maple syrup, minced ginger, garlic, and lime juice. If the sauce is too thick, add a teaspoon of warm water to achieve desired consistency.
Assemble your bowl by placing the roasted broccoli as a base, topping it with crispy tempeh, and drizzling over the peanut sauce.
Serve warm and enjoy your nutrient-packed, flavorful meal.
