Heat oil in a pan. Add onion, garlic, and ginger and saute till onion becomes translucent. (If you are adding green chilies, add it at this stage)
1 medium Onion, 3 cloves Garlic, 1 tablespoon Oil, 1 tablespoon Ginger
Add all the veggies now - potatoes, mushrooms, carrots, capsicum, cauliflower, and frozen green peas. Make sure the veggies are cut into very small bites so they cook faster, plus they are easy to eat. Else it will come out of the puff. You can also put them in your chopper.
1 large Potato, 3 large Mushrooms, 1 medium Carrot, 1 small Bell pepper, ⅓ cup Cauliflower, ½ cup Green peas
Cover this with a lid and cook on medium flame till the veggies are cooked through. This may take approx 5 to 6 minutes.
Add the ketchup or sauce, cilantro, garam masala powder, salt, and red chile powder and saute it. See that this filling or stuffing is dry.
1 to 2 tablespoon Tomato sauce, 1 teaspoon Garam Masala powder, 2 tablespoon Cilantro, Salt, 1 teaspoon Red chile powder
Switch off the flame and keep it aside.
