a) Bring a large saucepan of water to the boil with 1/2 tsp salt for the pasta.

a) Peel and grate the garlic (or use a garlic press).

b) Trim the root and dark green leafy part from the leek and discard. Halve lengthways, then thinly slice.

c) Finely chop the chives (use scissors if easier)

d) Drain the prawns. IMPORTANT: Wash your hands and equipment after handling raw prawns.

a) Meanwhile, add the rigatoni to the boiling water and bring back to the boil.

b) Cook until tender, 12 mins.

c) While the pasta cooks, heat a drizzle of oil in a large frying pan on medium-high heat.

a) Once the oil is hot, add the leek and prawns. Season with salt and pepper and stir-fry for 4-5 mins. Once cooked, remove the pan from the heat.

b) Next, add the garlic and stir-fry for 1 min more. IMPORTANT: The prawns are cooked when pink on the outside and opaque in the middle.

c) Stir in the water for the sauce (see pantry for amount) and veg stock paste. Bring to the boil, then simmer until slightly reduced, 2-3 mins.

a) Once the sauce is reduced, stir in the creme fraiche, bring back to the boil, then reduce to medium-high. Taste and add salt and pepper if needed.

b) Once cooked, drain the pasta in a colander, then add to the pan of creamy sauce along with the peas and heat through for 1-2 mins.

c) Stir through the cheese, then taste and season with salt and pepper if needed. Add a splash of water if you feel it needs it.

a) When everything's piping hot, spoon the creamy prawn pasta into your bowls and drizzle over the fresh pesto.

b) Sprinkle over the chives to finish.

Enjoy!
