Cook spaghettini according to package directions. Reserve 1 cup (250 mL) pasta water before draining.

Meanwhile, heat oil in a wok or large skillet set over medium heat. Stir-fry bok choy and peppers for 5 minutes or until softened. Stir in tofu, curry paste, soy sauce, garlic and ginger until tofu is coated. Add coconut milk and bring to a simmer.

Add spaghettini and cooking water to skillet. Toss to combine. Transfer noodles and vegetables to serving bowls and spoon over the curry broth. Sprinkle with cilantro and a squeeze of fresh lime juice just before serving.

Tips:
• Add more curry paste or hot pepper flakes to taste for a spicier curry.
• Replace the red curry paste with yellow or green curry paste to taste.
• The tofu can be replaced with cubed cooked chicken or small shrimp or omitted altogether if preferred.
