As written, edible, but has potential!
I made this as directed and it was edible. Being frugal and having spent 30 minutes making it, it was more worthwhile to eat it than toss it. I think with some changes it could be good. Next time I will cut the vinegar in half (way too much vinegar! The noodles and veggies were sitting in a huge pool of vinegar at the bottom of the bowl and it's all you could taste), add some soy sauce in place of the salt, add sesame oil and with sweet chili sauce or chili garlic sauce to give it a kick, and leave out the red onion, maybe sub in green onions and some ginger. It looked pretty, but was very bland as written, needed salt, spice, well, flavor. There is a lot leftover for lunch, so I may try to dress it up with the above suggestions.
Pros: healthy, doesn't heat up the house, vegetarian
Cons: bland, too much vinegar, kids wouldn't touch it
