Add all of the ingredients to the Instant Pot inner pot and stir well for a minute or so. Twist on the locking lid and select the Manual setting.I cooked this exact pasta for 4 minutes-you will want to cook your pasta for HALF of the time listed on YOUR pasta packaging. For example, if it says to cook it for 8 to 10 minutes, you might choose to set the pot for 4 or 5 minutes total. When the cook time has ended and the pot beeps, let it rest and natural pressure release for 2 minutes before carefully covering the vent with a damp cloth and releasing the rest of the pressure. *waiting those two minutes will help reduce the amount of starchy liquid that sometimes comes out of the vent when releasing the pressure. Carefully covering with a cloth is also an important step to prevent that possible spray from injuring anyone and making a mess. Remove the lid once it unlocks and stir the pasta (removing the separated tomato skins if you want). The sauce will thicken after resting for a few minutes. Top with a bit of fresh basil and tomato.
