Season your flour with herbs and spices of choice.
Bread the kohlrabi by dipping the slices in the egg or milk and then into the flour mixture.
Heat the oil in a pan ( I add enough to cover half of the slice) and cook until browned on both sides which only takes a few minutes. TIP: Do just one slice to start and taste it and adjust seasoning of flour mixture if needed.
You can bake the breaded slices as well, simply drizzle melted butter or avocado oil over the slices and bake at 375 or 400 until browned.
