Press the tofu for at least 15 minutes to remove excess water, then cut it into bite-sized cubes.
In a bowl, gently toss the tofu cubes with cornstarch, garlic powder, smoked paprika, salt, and pepper until evenly coated.
Preheat the oven to 400°F. Line a baking sheet with parchment paper and lightly spray or brush with olive oil.
Spread the seasoned tofu cubes on the baking sheet and place in the preheated oven. Bake for 25-30 minutes, turning halfway through, until tofu is crispy and golden.
While the tofu is baking, chop broccoli into florets and slice the bell peppers into strips.
Toss the broccoli and bell peppers with a little olive oil, salt, and pepper, then spread them on another baking sheet.
Roast the vegetables in the oven for about 20 minutes, or until tender and slightly caramelized, stirring halfway for even cooking.
Once both the tofu and vegetables are done, serve them together, and enjoy this nutritious and flavorful meal.
