In a large bowl blend the milled linseeds and chickpea flour with plant-based milk and use the spices to season the batter to your liking.
On a shallow plate mix the hemp seeds with the spices.
Flip the cauliflower slices in flour, then cover them with batter. Let the batter drip off slightly before pressing the slices into the hemp mixture on both sides, then transfer into a pan with hot oil to fry.
