Press the tofu for 15–20 minutes, then cut into ¾-inch cubes. Toss with 1 tablespoon of the olive oil, ¼ teaspoon of the salt, ¼ teaspoon of the black pepper, ¼ teaspoon of the garlic powder, smoked paprika, and cornstarch
If using an air fryer, air fry the tofu at 375°F for 14–18 minutes, shaking halfway through, until golden and crisp. If you don’t have an air fryer, spread the tofu on a parchment-lined baking sheet, leaving space between pieces, and roast at 425°F for 30–35 minutes, flipping halfway, until deeply golden and crisp around the edges. Broil for 2–3 minutes at the end if desired for extra browning.
In a separate bowl, toss the sweet potato, cauliflower, and mushrooms with the remaining 2 tablespoons olive oil, remaining ½ teaspoon salt, remaining ¼ teaspoon black pepper, and remaining ¼ teaspoon garlic powder. Spread the vegetables on a baking sheet in an even layer and roast at 425°F for 25–30 minutes, stirring halfway through, until tender and caramelized.
While the tofu and vegetables cook, whisk together the olive oil, lemon juice, maple syrup, Dijon mustard, and a pinch of salt and pepper in a small bowl until emulsified.
Add the Fresh Express® Romaine to a large serving bowl. Spoon the warm roasted vegetables and tofu over the romaine, sprinkle with pumpkin seeds, drizzle with the maple-lemon vinaigrette, and gently toss before serving.
