This recipe is really good with a few provisos. First and foremost cut the sugar by at least half. It is way to sweet with a half-cup sugar.
I also use Miracle Whip instead of mayonnaise. Next, there is no way you can make this in 30 minutes time. It takes me several hours at least to chop up all the veggies. I make up the sauce first, add the veggies as they are chopped up, and then cook, cool, drain, and add the pasta.
I use rotini instead of macaroni. The sauce sticks to it better. This is a very tasty salad. Try it, you will like it. Just be sure to cut the sugar by at least half.
