So being a vegetarian sometimes I cannot always get an udon without a fish sauce or other meat product in the broth. Due to that, I often make my own.
First chop up 1 leek, 5 carrots, and a green bell pepper and saute in sesame oil and pepper
Add a tbspn of red chili paste (or flakes if you dont have the paste lying around)
Then add in rainbow chard or other leafy green vegetable (bok choy is a good one to use)
After about 5 min, add 1/2 cup of soy sauce and 1 tbpsn of sesame seed oil
After about 5 min, add 1/2 a box of vegetable broth.
After about 5 min, add 1 package of Eden Organics Udon noodles
Cook until the noodles are tender.
When the noodles seem to have about 5 min left, add in broccoli.
Ladle into a bowl and say yum!
