Set the instant pot to sauté and add the oil.
Once the oil is hot, pinch squeezes out from the casing of the sausage meat into bite-size pieces. Brown the sausage until completely cooked. Once cooked, add the garlic and sauté for 2 minutes.
Add the vinegar and scrap the bottom of the instant pot removing any stuck particles.
Add the broth, spices, and dried tomatoes and stir.
Add the pasta and spinach. Don’t stir but press down into the broth.
Seal the lid and pressure valve. Cook on high pressure for 5 minutes. Manually release the pressure when done.
Remove the lid and add the butter, softened cream cheese, parmesan cheese, and half and half. Stir the pasta until the cheeses are melted and the pasta is fully coated.
Serve and enjoy.
