Fruit is pretty underrated as a good ingredient to spice up your pasta. Like most of the cold pasta salads, you'll want to avoid the noodles and go with shaped pasta varieties. Macaroni is a good place to start, or if you're into the twist, maybe try corkscrew pasta on for size. All kinds of fruits can be added to these pastas, depending on what kind of flavor you're after. Grapes, pineapples and mandarin oranges are all good and go well with nuts like sliced almonds or pecans. Cheese is another thing you can add to a cold pasta salad featuring fruit and nuts. Feta and blue cheeses are ideal candidates because the tangy taste goes well with fruit.
