Remove white parts of green onions, and finely chop. Chop greens into 2 inch pieces.

In a large heavy skillet over medium heat, mix coconut milk, 3 tablespoons soy sauce, brown sugar, curry powder, ginger, and chile paste. Bring to a boil.

Stir tofu, tomatoes, yellow pepper, mushrooms, and finely chopped green onions into the skillet. Cover, and cook 5 minutes, stirring occasionally. Mix in basil and bok choy. Season with salt and remaining soy sauce. Continue cooking 5 minutes, or until vegetables are tender but crisp. Garnish with remaining green onion.
