Prepare the soba noodles according to the package directions.
Assemble the salad by dividing the noodles into four bowls and adding equal amounts of the carrot, cucumber, bell pepper and cabbage. Top with warmed meatballs and serve with lime wedges, basil and mint leaves. Drizzle with dressing and serve.
For the Dressing
Mix the dressing ingredients in a small bowl or jar fitted tightly with a lid. You may wish to double the dressing if you like a lot of dressing.
If for some reason you don't have enough leftover meatball sauce to make the dressing, prepare a simple dressing by mixing 1/4 cup ponzu sauce with 1/4 cup rice vinegar, 1 teaspoon sugar (or to taste) 1/2 teaspoon dark sesame oil and the juice of 1 lime.
