Preheat your oven to 400°F.
Press the tofu for 15 minutes to remove excess moisture, then cut it into bite-sized cubes.
Toss the tofu cubes with cornstarch, a pinch of salt, and pepper until evenly coated.
Arrange the tofu on a baking sheet lined with parchment paper and drizzle with 1 tsp olive oil.
Bake the tofu for 25-30 minutes, flipping halfway through, until golden and crispy.
While the tofu is baking, preheat a separate baking tray with the remaining olive oil.
Chop the red bell pepper, zucchini, and broccoli into uniform pieces. Toss with a bit of salt, pepper, and a drizzle of olive oil.
Spread the vegetables evenly on the tray and roast in the oven for about 20 minutes, until tender and slightly charred.
Prepare the quinoa as per package instructions if not already cooked, ensuring about 0.75 cup is ready.
To serve, place a portion of quinoa on your plate, top with the roasted vegetables, and finish with a generous serving of crispy baked tofu.
