Put a kettle on to boil. Place 40g of reduced frozen Next-level chicken stock in a small saucepan on a medium heat, top up with 200ml of boiling kettle water, or to taste, and cook until thawed through.
Tip the remaining boiling water into another small saucepan and season with sea salt. Add 10 to 12 agnolotti and boil for 6 to 8 minutes, or until the pasta is soft but still has a slight bite, and the filling is cooked through. Transfer to a bowl using a slotted spoon, pour over the stock and drizzle over a little olive oil. Serve immediately.
