In the Instant Pot, press the Sauté button, add the olive oil and fry the vegetables for 3-5 minutes (in a conventional pressure cooker, sauté over medium heat).
Add the wine, stir and let bubble for a minute or two, lid off. Press Keep Warm/Cancel button.
Add seafood, stock, macaroni, mixed herbs, tomato purée, a pinch of salt and pepper. Stir with a wooden spoon while scraping the bottom to deglaze (remove any caramelised bits).
Press the Manual or Pressure Cook button, programme 5 minutes (in a conventional pressure cooker, bring to high pressure and cook for 5 minutes, in fact you may want to make that 4 as the psi tends to be higher).
Do a quick release after letting it rest for 30 seconds and then remove the lid and let it rest for a couple of minutes, it will be quite liquid to start with but will thicken rather quickly (see photos below). So finish setting the table, pouring a glass of wine or, if you prefer, clearing up.
Tweak the salt and black pepper and drizzle with the lime or lemon juice (if using) before serving.
