In a processor, process onion, garlic, ginger, walnuts and cilantro until finely chopped. Alternatively, cook the onions and garlic in 1/2 tsp oil until they are golden and then add to the processor.

Add the spices, salt, basil, rice, half of the cooked lentils and pulse a few times until well combined. Transfer to a bowl with the rest of the lentils. Add ketchup, oil, flax egg and mix everything until evenly mixed in. Mash a bit if needed and mix in. Taste and adjust salt, spice, herbs if needed. Add in the breadcrumbs or flour and mix in. Let the mixture chill for 10 minutes.

If the chilled mixture is too wet, add in more flour or breadcrumbs. The amount needed depends on the moisture in the veggies, the kind of lentils and just general mood of things in the mixture. Add more breadcrumbs or flour if too sticky wet. Add another flax egg if too crumbly to make patties.

Shape into 4 large patties. Pack well. Heat a skillet over medium high heat. Add a drizzle of oil and spread it around. Place patties on the skillet and cook for 4 to 6 minutes per side.

Serve with vegan ranch/avocado ranch or mayo or ketchup, mustard or other dressing of choice. Add some caramelized onions or other toppings.
