We love this pasta salad. It is simple and tasty. It is a great salad to take too get-to-gathers, or have on a hot summer's day. You just can't go wrong with anything you decide to put in this recipe. Any combination of the pkg. shredded cheeses can be substituted…… we like the cheese crumbles. Also, you can use pepperoni or turkey sticks instead of beef. It’s just whatever you like…it’s all good. You may need to add a little more or a little less oil & wine vinegar depending on your taste. Also, after I cooked the noodles, I cool them down quickly in a bowl of ice water for a couple of minutes; remove ice cubes and drain noodles in a colander. That isn't necessary to do, but it just helps cool the pasta down more quickly. I'm not sure about how many servings it makes. I think it could be about 10 to 12 servings, depending on what you may call a serving. At our house, it makes about 8 servings, Lol!
