Wash poha and drain all the water and let the poha get softer while you prep the other ingredients.
Boil two medium potatoes, you can do it in the instant pot, pressure cooker or stove top method. Steam the carrot slices, frozen green peas and green beans (if using).
I cooked them in the instant pot, added 3 cups of water into the stainless steel insert of the instant pot. Place the washed potato and close the instant pot lid to sealing position. Cook for 12 minutes and release pressure naturally. I also steamed the veggies along with the potatoes in the instant pot.
Heat a oil in a pan over medium heat and add finely chopped onion and green chili with a pinch of salt. Cook for five minutes till light brown. Now add garlic and finely chopped bell pepper and cook for 3-4 minutes.
Reduce the heat to low and add the red chili powder, turmeric powder, cumin powder, garam masala and amchur powder. Cook for 30- 45 seconds.
Add grated boiled potato, steamed veggies and salt. Mix it well.
Add the soaked poha and coriander leaves. Mash it well to ensure there are no lumps. Taste for seasoning and adjust salt or chili powder if needed.
Transfer it a bowl, let it cool for 10 minutes and cover it with a cling wrap. Refrigerate for 15- 20 minutes (not more than that, if not the dough will get harder).
Remove and mix it again. If the mixture is sticky, add some bread crumbs. Make equal size balls and slightly flatten it to make a patty.
