I was going to submit this recipe when I found yours. Mine is the same except for the addition of 1/2 cup sliced green onions. It is a great summer salad or lunch. Perfect for potlucks. Also, if you are unable to find the refrigerated tortellini it is OK to use the dried version in the pasta section. Just cook it according to the package directions and proceed with the recipe.
Did this twice in July. It traveled well, and both parties loved it. Something different, and the colors were great for the 4th. I used "kitchen sink" dressing, and it was still fabulous. Will definitely be making it again. Also, a good way to get a little more vegetables into our diets!
