Cheese Tortellini Pasta Salad

I was in the grocery store one night and decided I wanted to get the ingredients to make some pasta salad. I literally googled 'pasta salad recipes' on my blackberry and read through a few and settled on this one (on myrecipes.com). What a find! This is absolutely, postively, hands down the BEST pasta salad I have ever had.
Since that night, I have made this salad so many times, my husband and I both love it, and every time I have taken it to an event or potluck, several people ask for the recipe. Make this and enjoy- and I promise you will thank me!
