Cook the noodles as the label directs. Drain and set aside.
Meanwhile, heat a large pot over medium-high heat. Add the curry paste and cook, stirring constantly, until it turns deep red, 30 seconds to 1 minute. Stir in the coconut milk, ginger and brown sugar. Increase the heat to high and bring to a vigorous simmer. Stir in the squash, haricots verts and bell pepper. Cover, reduce the heat to medium and cook until the squash is just tender and the beans and bell pepper are crisp-tender, about 10 minutes.
Stir in the fish sauce and season with salt. Stir in the tofu and cook, uncovered, until warmed through, about 1 minute. Divide the noodles and curry mixture among bowls. Top with basil and serve with lime wedges.
