What is a salad pasta that starts with an r?

There isn't a common salad pasta that starts with the letter "r". However, there are a few possibilities depending on what you're looking for:

* "Romaine" is a type of lettuce often used in salads, but not a pasta.

* "Rigatoni" is a pasta shape, and can be used in cold pasta salads. However, it doesn't have a strong connection to salads like some other pasta shapes.

* "Radicchio" is a leafy green often used in salads, but not a pasta.

It's possible you're thinking of a specific salad recipe that uses a different type of pasta. Could you provide more information about what you're looking for?
