Place pasta in the inner pot. Pour enough vegetable broth, or water, so the noodles are just covered. Add in 2 tsp of salt. Stir to ensure all the noodles are coated.
Pressure Cook on High for 3 Minutes. Quickly release any remaining pressure, careful to watch for any pasta foam coming from the release valve. If so, close the valve for 30 Seconds and then continue releasing pressure.
While the pasta is cooking, add tomatoes, garlic, basil, olive oil, and remaining salt.
Strain the cooked pasta and rinse under cold water. Add the cooled pasta to the mixing bowl. Stir to combine and season with black pepper and additional salt to taste.
