I've been making this one:

1 box pasta (Mueller's bought on sale 2/$3, with a $1 off 3 coupon = $.33/box)
1 bottle Kraft Ranch dressing (FREE w/ $1.50 off coupon)
1 diced green pepper ($.50 at SAL)
1 package Hormel pepperoni - diced (bought on sale 10/$10 11th free with a $.75 off q) so $.14
1 can black olives $.65/can at Sam's Club
1/2 cup parm cheese (on sale 2/$4)
1 8oz bag shredded mozz or co-jack cheese ($1.50 on sale)
1/4 cup finely diced onion
1 cup diced tomato (optional)
1 head of broccoli chopped into bite sized pieces (only when it's on sale 10/$10)

I like the ruffles for pasta salad because they hold the dressing and cheese really well, but any noodle shape will work.
