Gather all the ingredients. For the potatoes, you may boil them in advance. I boiled the potatoes for 2 whistles and simmer for 5-10 min.
Mash the boiled potatoes in a large bowl. Add grated Pumpkin to it. Add all the spices, salt, green chilly(Chopped fine), grated raw mango, bread crumbs and Besan. Combined it into a thick mixture. If you feel the mixture is runny, add more besan or bread crumbs.
Make round tikkis. You may apply oil on your hand to make round tikkis
Deep fry them in batches. Make sure to add them to hot oil and simmer after a while. It takes around 2-3 min to get it fried from both sides. When you take it out, again full the flame or else tikki will seep in lot of oil.
Take the fresh buns. Apply Mayo, Ketchup on the inner sides of the buns. Place tikki, Onion rings, cucumber tomatoes over Tikki. Apply the cheese slice. Cover the top bun and ENJOY!!! Your Veg Pumpkin Aloo Tikki Burger is ready!!
