A friend gave me this recipe years ago, and it has been my go-to for potlucks ever since. It's super easy, and can be thrown together in practically the amount of time it takes to boil a pound of pasta.
Killer Pasta Salad
1 lb of your favorite pasta (I use Tri-Color Rotini)
Italian Dressing (about 2/3 of the bottle to your taste)
2 Tbls of McCormick Suddenly Salad Seasoning
1 English Cucumber
1 pack Grape Tomatoes
1 can Black Olives
Grated Parmesan Cheese (the fresh works best)
Cook pasta according to package directions. Drain into a colander and rinse under cold water. Pour pasta into a bowl. Pour Italian Dressing over the top and add the seasoning, diced veggies, and some of the cheese. Refrigerate overnight if possible (it helps the pasta to absorb the flavor and make it even more KILLER). Before serving, add more dressing if needed, and sprinkle cheese on top.
