You can prep the pad thai ingredients and make the dressing a few hours ahead (dress it just before serving)
Whisk together peanut butter, lime juice, soy sauce, 2 tablespoons water, ketchup, sugar, ginger, and red pepper.
Place squash, sprouts, bok choy, carrots, mint, tofu, and 1/4 cup of the cilantro in a large bowl. Add dressing; toss to coat. Divide mixture evenly among 4 serving plates or shallow bowls; top with peanuts and remaining 1/4 cup cilantro. Serve immediately with lime wedges.
