Place the chopping blade inside the food processor bowl. Add chickpeas, onion, garlic, ginger, green chilies, cilantro, dry spices, and rolled oats to the food processor bowl. Pulse for 1 to 2 minutes or until all the mixture is evenly processed. Carefully remove the chopping blade.
Add the grated carrots into the bowl and mix well. Using a spatula divide the burger mixture into 4 parts and form into ¾ inch thick patties.
Place a nonstick frying pan over medium heat. Add half of the oil. Once the oil is hot, place the four burger patties in the pan and cook for about 3 to 4 minutes side.
Pour the remaining oil over the burgers and carefully flip each patty with a silicone spatula. Cook for another 3 to 4 minutes as both sides get crispy and golden brown in color. Remove the Burgers from the skillet and place them on a platter.
Wipe down the skillet and heat 1 teaspoon of oil. Place 4 bun halves with the middle side on the skillet. Cook for 1 to 2 minutes as the buns get a bit toasty and warm.
Make the Sriracha Mayo by combining the mayonnaise with sriracha.
Place the bottom side of the burger on a platter. Spread 1 tablespoon of sriracha mayonnaise over it. Place the chickpea burger on the bun along with a slice of onion, tomato, and lettuce. Put the top lid of the bun over it and enjoy.
