Cut off stalks, set the green fronds to the side to use for garnish afterwards. Cut off root end. Halve fennel bulb lengthways. Cut at a diagonal angle in a triangular shape, from both sides, underneath the tough core to remove it. Separate the fennel layers. Slice into strips or dice.
Use the fennel slices instead of tortilla chips and enjoy with dips, or use the diced fennel in soups and stews to add a really rich, earthy flavor to your meals.
