I'm not a huge fan of ranch, but i do like it now and then. I like it on jacket potatoes instead of sour cream and i also make a pasta salad with it.
You just take some cooked, drained and cooled spiral noodles or whatever, some Hidden Valley ranch dressing (or whatever brand, i just like that one best), some black olives, some pimento, some mushrooms and toss it all in a bowl.
It's better the second day, but still lovely and so easy. I've taken it to loads of pot-luck type things and it's always gone before i know it.
