I dice up some onion, green and red pepper, a little jalapeno, some
mushroom, diced tomato, and mix it in a 1 gallon ziploc bag with
italian salad dressing and a wedge of parmesan that I process until it
is completely grated. I add a lot of fresh ground black pepper. I
will often let that sit in the fridge for a couple hours so the
flavors mix. Then I boil some pasta, and once it is cooked I drain it
and pour it into ice cold water. Once the pasta is cold, I drain it
well, and add it to the ziploc bag, zip the bag closed, and mix
everything together.
