I made my pasta salad this morning for the barbecue we're having this afternoon. I think this pasta salad is basically the same as the one my parents made growing up... it's delicious!
1 lb rotini pasta
1 can of olives, whole or sliced
1 package of mozzarella cheese, however you want to buy it (I don't think sliced would work well, though)
A generous few handfuls of shredded parmesan cheese
A package of those cute little grape or cherry tomatoes
A package of slices of salami
1 bottle of Italian salad dressing
Cook the pasta as instructed on the package. As soon as the pasta is al dente, drain it, then rinse it in cold water until it is cool.
While the pasta is cooking, slice the olives (if necessary), cut the mozzarella cheese into cubes or oddly-shaped pieces as is your wont, cut the cute little grape tomatoes in half, and slice up the salami into thin slices or whatever shapes you want. Add all of this to the bottom of the bowl you are going to put the pasta in, along with half the parmesan cheese.
Once the pasta is done and is cool, add it to the bowl. Add the other half of the parmesan cheese, along with salt and pepper. Mix everything up using your hands or a spoon, or whatever.
Add the italian dressing to taste - I'd probably use 2/3 of the bottle, but it's up to you. Make sure the dressing is evenly distributed throughout the salad. Refrigerate.
If you set it in the fridge for awhile, make sure to mix it before serving it, because the dressing settles on the bottom.
