Bring a pot of water to a boil. Add the soba noodles and cook according to the package instructions. Drain and rinse with cold water.
Prepare the peanut sauce and set aside. Chop all of the veggies.
Add the noodles, veggies and 1/2 of the peanut sauce to a VERY large bowl. Toss to combine. Add more peanut sauce to taste - or reserve to add to leftovers.

Notes
If you're making this for meal prep, I would leave the peanut sauce out completely and just add it to each serving before eating.
