Amounts of ingredients are variable depending on how much you want to make.

fresh broccoli
carrots
red onion
pasta - the ruffly one
mayonnaise - about 1/2 cup
bottle of Paul Newman's Caesar Salad Dressing

Cook pasta and drain. You can use whatever pasta you want.
Cut broccoli stems off so you just have the florets.
You can very lightly steam the broccoli if you want, or leave it raw.
Use your potato peeler to do shavings of carrots, or julienne them.
Chop onion. You can use whatever onion you like.
Mix all the ingredients in a bowl.

Note: Depending on how much of this you are making, you might not need the full bottle of salad dressing. If I'm doing a regular size box of pasta I sometimes only use 3/4 of the regular sized bottle of dressing. But it totally depends on your taste and the amount of ingredients you use. So start with smaller amounts of mayo and salad dressing, mix it up and taste it, then adjust accordingly.

Best after chilled for a few hours.
