01 - Pat the tofu dry thoroughly with paper towels and cut into 3/4-inch cubes. Toss the cubes with cornstarch in a bowl until evenly coated on all sides. Heat vegetable oil in a large nonstick skillet over medium-high heat. Add the tofu cubes in a single layer and fry until golden and crispy on all sides, turning occasionally, about 8 to 10 minutes. Remove the tofu from the skillet and set aside on a plate.
02 - In a small bowl, whisk together the fresh orange juice, soy sauce, maple syrup, rice vinegar, minced garlic, grated ginger, and orange zest until well combined. Pour the mixture into the same skillet used for the tofu and bring to a simmer over medium heat. Stir in the cornstarch-water slurry and continue cooking, stirring constantly, until the sauce thickens and becomes glossy, about 2 to 3 minutes.
03 - Return the crispy tofu cubes to the skillet with the thickened orange soy glaze. Toss gently to coat each piece evenly. Continue cooking for 1 to 2 minutes more, allowing the sauce to adhere and caramelize slightly on the tofu. Remove from heat and set aside.
04 - In a separate pan, heat sesame oil over medium heat. Add the baby spinach or kale and sauté, stirring frequently, until just wilted and tender, about 2 to 3 minutes. Drizzle with soy sauce and sprinkle with toasted sesame seeds. Toss to combine and remove from heat.
05 - Divide the cooked rice evenly among 4 bowls. Top each bowl with the sticky orange soy tofu, sautéed sesame greens, julienned carrots, and sliced green onions. Garnish with additional sesame seeds and serve with lime wedges on the side if desired.
