"No Chunky Monkey"

Hi:

Need help:

Some companies try to let their values guide their operations, and make products that are designed to enhance health and well-being. No Chunky Monkey, thanks.

What does "No Chunky Monkey" mean here?

Ben & Jerry's Ice Cream is an American institution, with flambouyant promotions, a '60s-style Peace & Love mission, and some sinfully-rich flavors, all colorfully named. Peace Pops, Cherry Garcia, Chunky Monkey. Just putting a spoon into Chunky Monkey adds to your waistline.
