Heat the olive oil in a shallow pan over medium heat and sauté the zucchini until golden, about 10 minutes.
Add the garlic and prawns and cook until the prawns turn pink, about 2 minutes.
Add the tomatoes, fish stock, wine, lemon juice, and saffron extract; cook for 5 minutes, or until the liquid reduces by half.
Meanwhile, bring water to a boil, minimum of 1 litre per 100g of fresh Pasta. Add the salt to the water once it boils.
Fluff the Pasta up with your fingers before dropping into the boiling water, cook until the pasta is al dente, only a minute or two max for Tagliolini.
Drain, reserving 1/3 cup of the pasta cooking water.
Transfer the pasta and reserved cooking water to the pan with the prawns and toss for 1 minute over medium-high heat.
Transfer to a bowl, garnish with the parsley, and serve hot.
