We need 1.5 cups of cooked chickpeas for this recipe. Either you can use canned chickpeas/garbanzo beans, or you can use homemade ones too. Soak 1 cup of dried chickpeas for 8 hours and pressure cook for 3 to 4 whistles by adding sufficient water. If using Instant Pot, cook at bean/chili mode with sufficient water. Drain the water and take the required amount of chickpeas. You can use the remaining chickpeas for making hummus, vegan bunny chow, chana masala.
Steam 200 grams of potatoes and let it cool. Peel the skin and mash them roughly. I steamed the potatoes in my Instant Pot using the steamer basket. Pout 1.5 cups of water to the inner pot and place the tall trivet or egg rack. Now place the potatoes inside the steamer basket and place them on top of the rack. Pressure cook for 5 minutes and release the pressure quickly after 10 minutes.
Prepare the phyllo cups/shells as per the package instructions. I used Athens mini fillo dough shells. It is pre-baked, but I prefer to bake it again to make it crisp. Preheat the oven to 350 degrees F, bake the shells for 3 to 5 minutes at 350 degrees F, and set them aside. Let it cool a bit. (As the quantity is more, you might need two baking trays or bake in batches)
Parallelly, add the cooked chickpeas, mashed potatoes, onions, green chutney, sweet chutney, pomegranate arils, chaat masala, red chili powder, cilantro, black salt, and regular salt.
Combine them all and check for salt and spices at this stage. Adjust as needed. The aloo chana chaat is ready.
Add approx two to three tsps of the prepared aloo chana chaat inside the phyllo shells. Sprinkle the sev and serve immediately.
Notes
There is no set measure for the aloo chana chaat filling. Adjust the measure and ingredients to taste and preference.
You can also sprinkle sweet chutney or green chutney or yogurt on top of the chaat bites along with sev.
You can skip potatoes and make the filling only with chickpeas, both white and black works. And you can do it vice versa too. Skip the chickpeas and make the filling only with potatoes.
