Here is a great recipe http://www.food52.com/recipes/1666_arugula_pear_and_goat_cheese_salad_with_pomegranate_vinaigrette
If you don't want a salad, you can make pasta and toss it with arugula. The warm pasta will soften the arugula.
It is wonderfully versatile and the optiions are endless. Use it the way you would any kind of lettuce or green in a salad.
