Pluck and rinse the spinach well in lots of water thrice. Transfer them to a colander to ensure all the water has drained. Keep these aside.
Rinse and boil potatoes in a pot or cooker until fork tender (just cooked without turning mushy). To boil in pressure cooker, cook for 3 to 4 whistles. To cook in Instant pot, I cut each potato to 2 pieces and pressure cooked them 6 minutes.
Cool them completely and peel the potatoes.
Pour 1 teaspoon oil to a pan and heat it. Saute ginger & green chilies for 30 seconds.
Then add green peas and saute them for 4 to 5 mins, until the raw smell goes away.
Add palak & saute on a medium high flame until it wilts off completely. (Or If you are on a low oxalate diet, then you can also blanch the palak in 3 cups hot water, drain completely and use it to blend with green peas.) But the sauteing method tastes best.
Turn off the stove and cool all of these. Add them to a small grinder/ blender along with coriander leaves.
Blend all of them to a smooth paste without adding water.
Crumble the potatoes in a mixing bowl & add the ground green peas and spinach paste.
Add salt, garam masala, chaat masala, roasted gram flour and bread crumbs.
Mix all of them to a non-sticky dough. If the dough turns sticky, then add more bread crumbs to absorb excess moisture. This is optional.
Divide the dough to 10 portions. Roll them to balls. Flatten them to shape like patties or kababs. Keep them aside.
To pan fry: Heat a griddle with 1 tablespoon oil. When the pan turns hot, place the hara bhara kababs on the pan and pan fry them until golden & crisp.
To grill them in oven: Preheat the oven to 200 C for 15 minutes and place the patties on a greased tray. Brush the kababs with oil and grill them for 10 mins on each side. Adjust the timings as needed.
To air fry: Brush them with oil and place them in the basket. Air fry at 180 C for 10 mins on each side. After 10 mins check and flip them to the other side and air fry for another 10 mins. Adjust the timings as needed. If your air fryer needs preheating, preheat it before air frying them.
Serve hara bhara kabab with yogurt cilantro chutney, ketchup or green chutney.
