I found this recipe for pasta salad a few years ago on allrecipes.com and it quickly became my absolute favorite pasta salad ever. I used to call it Antipasto Pasta Salad, but my mom said that when we lived up north a similar salad was known as Manhattan Deli Salad, so that's what I like to call it now.
With hunks of salami, pepperoni and asiago cheese, it's hearty enough to enjoy on it's own, but also makes a great accompaniment to hoagies, burgers and dogs or barbeque ribs.
One important note: the asiago is key! Don't substitute it! You can find it in the fancy cheese case or, usually less expensive, at the deli. I have the deli counter cut me a few slices about a half inch thick (same goes for the salami and pepperoni) which makes it easy to then cut into cubes. Sometimes you end up with a little more or less than called for, but it's okay to be a little off in the measurements.
I've had no problems making this salad ahead of time, but if you do be sure to take it out of the fridge a little while before serving to let the dressing loosen up a bit. This one's a winner and I guarantee you'll love it!
