Use a mandoline slicer or a sharp knife to slice the turnips, radishes, and fennel bulb.
Heat the solid cooking fat in the bottom of a skillet on medium heat. When the fat has melted and the pan is hot, add the vegetables and cook, stirring for 5-7 minutes or until just soft.
Add the lemon juice and sea salt and toss to combine.
Garnish with lemon zest and fennel fronds and serve warm.
