Combine chilli, garlic, white and lime green part of lemongrass and 2 tablespoons of the oil in a small processor. Process until finely chopped. Add 2 tablespoons of the peanuts and process to a paste (a little texture still in peanuts is good). Remove to a bowl.
Cook the noodles following packet directions. Drain, keep warm.
Heat a wok over a high heat until hot. Add 2 teaspoons of oil to the hot wok. Wash the Fioretto®, leaving water clinging. Add to the wok with 1 tablespoon of the paste, stir-fry for 2 minutes. Add 1 teaspoon of water, cover the wok and cook for 1 minute until Fioretto® is tender, remove to a plate.
Add remaining oil and mince, stir fry for 2 minutes until mince changes colour. Add remaining peanut lemongrass paste and stir-fry for 3-4 minutes or until the paste is aromatic. Add Fioretto®, stir-fry for 1 minutes. Remove from the heat, and squeeze over the lime halves.
Divide noodles among serving plates. Top with Fioretto® mixture, garnish with extra peanuts and chilli. Serve.
