Cook the noodles according to package directions.
Once cooked, drain them in a colander but do not rinse.
Set the noodles aside and return the empty pot to the stove.
In the same pot, combine the vegetable broth and peanut sauce over medium-high heat.
Whisk together and bring the mixture to a boil.
Stir in the frozen stir-fry vegetables and the cooked noodles. Return the mixture to a boil, then immediately reduce the heat to low. Allow it to simmer for 2 to 3 minutes, or until the vegetables are fully heated through.
Divide the noodle and broth mixture evenly among four soup bowls.
Garnish generously with the chopped dry-roasted peanuts before serving.
