Chop the spinach roughly(not finely).
Dice chop onions and potatoes into small pieces
Add chickpea flour, spices and mix well
Add little water as needed to make a batter
Heat oil on low to medium heat in a wok
Use a medium-slotted spoon to drop small amounts of batter in the wok (I use another small spoon to glide it gently into the oil)
Let them sit on a paper towel to let the excess oil drain
