Wash, rinse and soak adzuki beans for at least 4~6hours. Soak for 4~6 hours or overnight and then boil them for 30~40 minutes until very soft.* Drain the excess water and let them cool for a little bit.
Cook rice separately and keep ready.
In the meantime, heat 2 teaspoons oil in a saute pan and cook until translucent about 3~4 minutes. Next add garlic clove and cook for 1 minute.
Next add the chopped peppers and cook until tender, about 6~8 minutes. Season with salt, chili powder, garam masala & kasoori methi. Mix well and turn off the heat. Let the mixture cool slightly.
Combine the beans, rice and the onion mixture in the food processor. Process until the mixture comes together.
Remove it into a bowl and add bread crumbs, flax egg, flour and form a smooth dough that doesn't stick to hands.
Take ¼cup of mixture and form into burgers. I was able to make 10 medium size patties.
At this point, burgers can be made right away or can be frozen for later.*
Heat 1tbsp oil in a saute/ grill pan. Cook the burgers on medium-low flame until golden on both sides and cooked through, about 3 minutes on both sides.
Serve on sandwich buns with the choice of toppings.
