Mash peas in a bowl and add the shallots, scallion, parsley and chili sauce. Heat a skillet on medium heat. Add olive oil. Wait a few seconds and add mushrooms. Saute just a few minutes until nicely browned but not cooked down. Add toasted walnuts, the garlic and sauté for about a minute. Remove from heat and add to pea mixture. Blend well with a fork or hands. The mixture should be a little dry and easily shaped into patties. Form patties to desired size.

Heat a heavy skillet, cast iron is best with a good coating of vegetable oil. Put the half cup of flour on a dish. Take each burger and dredge in flour. Place in hot skillet and cook until a nice brown crispy coating appears. Turn carefully. When done, place on a bun with your favorite burger toppings, or serve with a salad for a delicious light meal.
