Heat broth in a saucepan over medium heat until hot, about 5 minutes.
Bring a large pot of lightly salted water to a boil. Cook udon noodles in boiling water, stirring occasionally, until noodles are tender yet firm to the bite, 10 to 12 minutes. Drain.
Pour broth equally into 4 serving bowls and add noodles. Top each bowl with cabbage, bean sprouts, carrots, celery, cucumber, jalapeno, pea pods, chile-garlic sauce, and hoisin.
