This delicious dip is unlike anything you have tasted. The smooth cannellini beans and creamy avocado are perked up by the briny preserved lemon. We add cilantro and mint for freshness, and cumin and coriander for some subtle spice. Serve this with toasted pita chips for a great party snack or use it as a stuffing for tomatoes for a light dinner. You could also include it in a mezze platter or in a veggie sandwich. The possibilities are endless! You can make your own preserved lemon but we love the pickled lemon from Alili, a purveyor of Moroccan specialty products.
