Finely mince the garlic and chili. If using ginger, peel and grate it. Slice the green onions, separating the white parts from the green tops (set the green parts aside for garnish). Cut the red bell pepper into thin strips.

Wrap the tofu block in paper towels or a clean kitchen towel and press gently to remove excess moisture. Cut into bite-sized cubes or rectangles. The drier your tofu, the crispier it will get when cooked.

In a small bowl, whisk together the soy sauce, lime or lemon juice, reserved noodle water, five-spice powder, and sugar until combined. Heat the oil in a wok or large skillet over medium-high heat. Add the tofu pieces and cook undisturbed for 2-3 minutes, then flip and continue cooking until golden and crispy on multiple sides (5-6 minutes total). Add the garlic, ginger (if using), chili, white parts of green onions, and bell pepper. Stir-fry for 2-3 minutes until vegetables are crisp-tender. Add the cooked noodles and sauce, tossing everything together until well coated and heated through.
