01 - Preheat the oven to 400°F. Alternatively, set an air fryer to 375°F for a crispier result with less oil.
02 - Pat the tofu cubes thoroughly dry with paper towels. Place in a mixing bowl and toss with cornstarch, soy sauce, and sriracha until evenly coated.
03 - Arrange the seasoned tofu on a parchment-lined baking sheet or air fryer tray. Drizzle with neutral oil and bake for 20 to 25 minutes, flipping halfway through, until the edges are deeply golden and crisp.
04 - Cook the brown rice, quinoa, or farro according to package directions if not already prepared. Fluff with a fork and set aside, keeping warm.
05 - Julienne the carrot, thinly slice the cucumber and bell pepper, shred the red cabbage, and slice the scallions. Arrange within reach for easy assembly.
06 - In a small bowl, combine the soy sauce, rice vinegar, maple syrup, toasted sesame oil, and sriracha. Whisk until smooth and well blended.
07 - Divide the warm grains among four bowls. Arrange the prepared vegetables over the grains, then top generously with the hot crispy tofu. Drizzle with the spicy sauce and scatter with toasted sesame seeds and fresh herbs. Serve immediately with lime wedges on the side.
