Pre-packaged noodle soups are a kiddie favorite because they're quick and tasty. The downside is that the prepackaged versions aren't exactly healthy with all of that sodium loaded into their spice packets. Using this soba noodle base with the ponzu adds a rich tangy flavor. Using only a bit reduces much of the sodium. It only takes a few minutes to make your own, and it’s fun to serve them in a cup alongside kid friendly chopsticks. You can add different vegetables, shrimp or crab to make this heartier or get a protein bump. So good as an after school snack or a meal.
