Put the prawns in a sieve and let them thaw for about 1 hour. Peel the prawns, remove the gut, wash and pat dry. Wash the zucchini, grate dry and peel into strips with a julienne peeler.
Peel garlic and dice finely. Wash 1 lemon and grate dry. Grate the peel. Halve lemon and squeeze out juice. Wash parsley, shake dry and pluck leaves from the stalks.
Season prawns with salt and pepper, heat oil in a pan. Fry the prawns for about 5 minutes, turning them over. Remove and add the zucchini pasta to the pan. Fry for about 2 minutes while turning, season with salt and pepper.
Add the prawns, lemon peel and lemon juice, continue to cook for about 2 minutes. Wash the remaining lemon, grate dry and cut into thin slices. Mix parsley into the zucchini pasta and arrange.
