Now add the garlic, chicken breast, oregano and basil. Cook until the chicken is browned.
Season to taste and add the pasta sauce, stock and pasta. Push the pasta down into the liquid, but do not stir.
Put the lid on the instant pot and set on high pressure for 4 minutes. leave under pressure for a further 4 minutes and then do a quick release.
Stir in the parmesan and while its melting make the topping by blitzing the bread, cheese and butter together.
