Why not try some celery or carrot sticks, cauliflower florets or even slices of apple and radishes? These will all make tasty dipping vegetables and will add some variety to your snack.

It's often a good idea to mix different tastes like this (such as mixing apples and peppers, which are sweet, with celery and radishes, which have a very different taste). This way you can make very interesting food combinations.
