mozzarella cheese (if you want the BEST results spend a few dollars more and get bufula mozz)
basil (preferably fresh)
salt to taste
*I kind of "eye-ball" all of these ingredients--- so I don't have exact amounts. Sorry.
boil water and add pasta. penne usually cooks for about 11-12 minutes until al dente.
meanwhile cut tomatoes and cheese into bite sized pieces. combine in a bowl with basil and mix in olive oil.
when pasta is finished, drain, add olive oil and salt to taste and then combine tomato mixture. perfetto! best pasta ever :)
