Dice the onion and slice the sausage, set aside.
Chop the half pepper up into smaller pieces so it is easier to blend. Blend tomatoes, sundried tomatoes and bell pepper until smooth then set aside.
Turn your Instapot to the saute setting. When the display says HOT add in the garlic and diced onion and saute for 1-2 minutes, until slightly soft.
Add in the pasta noodles (dry). Pour the broth and blended tomatoes around the pasta.
Add in the seasonings and stir to combine, top with the cooked sausage.
Cover the pot and secure the lid. Make sure the valve is set to sealing. Set the pressure cook button to 5 minutes and start it (set to 6 if you like the pasta softer).
When the time is up let the pot sit for 3 minutes and then move the valve to venting. Remove the lid, it will be water-y, that is okay.
Turn the pot to saute. Add the cream cheese into the pot. Stir until melted.
