Toor dal -1/4 cup
Spinach – 1bunch
Fennel seeds-1/2 tsp

METHOD:
Soak the Channa dal and Toor dal for 2 hours.
Drain the water and grind this along with red chilli, salt, fennel seeds, cumin seeds, garlic and asafoetida.
Grind them coarsely.
Add turmeric powder, garam masala powder, chopped onions and finely chopped and cleaned spinach to this.
Mix it nicely with hand so that ground dal and greens mix together to hold as balls. Take a portion of the batter and slightly flatten this with your hands.
Normally keerai vadai is slightly bigger than the regular masala vadai.
Heat oil in a wok for deep frying, when it is hot carefully place the patties to the oil. do not put too much in a batch.
Flip it after few minutes and cook on a medium flame.
Do not keep the flame too high, the inner side will not get cooked.
Do not keep it too low also. It will make the vadai soggy.
When it turns a golden brown colour, drain this in a kitchen towel and enjoy hot with a cup of coffee or tea.
Note: You can add few spoons of water if you need them while grinding.
Remember we have water in spinach and chopped onion, so better grind without water.
