To a small mixing bowl, add mayonnaise or Greek yogurt, mustard, olive oil, garlic, chilli flakes and black pepper. Taste test and add salt if needed. If your mayo is not sour add lemon juice as well. Mix and refrigerate until needed later.

Pour 2 ½ to 3 cups water to a steamer/ cooker or a pot. Place a trivet or a rack inside the pot. Cover and bring the water to a boil.

Meanwhile rinse potatoes & French beans. Trim off both ends of French beans and fine chop them. Peel and cube potatoes to 1 inch pieces. Add them to a steamer basket and place them in the steamer.

Steam them until half done for about 5 to 7 mins. Meanwhile, peel and chop carrots to 1 inch pieces.

When the potatoes are half done, transfer carrots & peas to the steamer. Cover and steam them until potatoes are done completely and fork tender. Even peas and carrots should be done by now.

Cool all these steamed veggies and transfer to a mixing bowl. Once cool mash them well and then add garam masala, coriander powder, green chilies, coriander leaves and salt.

Mix all of them. You will have a mushy and sticky mixture. To this add, bread crumbs or powdered poha or flour in batches only as needed.

The mixture for the patties must not be too soggy or too moist. Slight stickiness is alright but it has to be firm. If not add more bread crumbs. Check pictures in the step by step photo section in the post.

Taste test the mixture and add more salt or any seasoning if you prefer. Divide the dough to 4 to 6 portions depending on how thick or thin you want the patties to be.

To a small mixing bowl, add gram flour or corn starch to make the batter. Add a pinch of salt & pour water just enough to make a fairly thick batter. Do not make the batter runny as the excess moisture will be soaked up by the patties making them too soft.

Pour bread crumbs or panko crumbs to a wide bowl or plate.

Take one portion of the vegetable patty mixture and flatten it to the same size as your burger bun. If the mixture is sticking. Place the patty in some flour or corn starch. This way make all the patties and place them aside in a plate.

Dip each patty in the batter completely and then place them in the bread crumbs. Coat the patty well with the crumbs including the sides.

This way coat all the patties and set them aside. Rest these for 10 mins so the crumbs stick well to the patties and don’t mess the oil/ pan while frying.

Rinse each lettuce leaf separately under a slow stream of running water. You may also sprinkle a solution of 1 part vinegar mixed with 3 parts of water. Rinse well and let them sit of kitchen tissues so all of the water drips away.

Slice onions and tomatoes to round thin slices. If needed deseed the tomatoes.

Refer notes section to bake or air fry the patties. To pan fry, heat a pan with 1½ to 2 tablespoon oil. Let the oil become hot, then place 2 to 3 patties as many as your pan fits. Rotate the patties with your fingers gently to coat the patties with the oil.

Fry them on a medium high heat until the base turns golden and crisp. Flip them gently and pour 1 ½ to 2 tablespoons oil as needed. Fry until crisp & uniformly golden. For a proper golden to brown crust, increase the flame the last 2 mins.

To shallow fry, pour ½ cup oil to a small pan and heat it. When the oil becomes hot, gently place the patties in the hot oil & fry until golden.

Gently turn them to the other side and fry until golden & crisp. Remove them to a wired rack to cool slightly before assembling. To make cheese burgers, place cheese slices over the very hot patties.

Once done with frying the patties, transfer the oil to a cup. Slice each bun to 2 parts and spread some butter on the buns if you prefer. Toast them in the same hot pan. Remove them and set aside.

Before assembling please recheck - Lettuce should not have any water dripping, patties not too hot and the burger bun is also not hot.

Place the toasted bun in a serving tray and then the veggie patty. Optionally spread the burger sauce we made earlier or some ketchup to keep the patty in place. However this is optional & skip if you want your patty very crisp.

Place the lettuce, then the onion and tomatoes. Optionally drizzle some sauce over the lettuce and onions if you like. Spread more sauce over the top slice of your bun and place it over the burger.

Burgers are ready to serve. Potato wedges, boiled corn, cheese balls are some of the great sides.
