Set a large pot to medium heat and add oil. Once the oil is hot add broken up noodles and toss to coat in oil. Continue to cook until noodles are golden brown, about 3 minutes.
Let mixture simmer for 1 minute. Add the rest of your stock and set heat to high. Add zucchini and cook noodles at a low boil until noodles are al dente and zucchini is tender. Stir often. Season.
Serve with a wedge of lime so everyone can add as much lime juice as they like.
