Steps

  1. Simmer the brown lentils in the water in a small pot for 25 minutes until tender, then drain well and let cool slightly.
  2. While the lentils cook, toast the walnuts in a dry skillet over medium heat for 4 minutes until fragrant, then chop finely.
  3. Heat half the olive oil in the same skillet over medium-high heat. Add the onion and cook 4 minutes, then add the mushrooms and cook 10 minutes, stirring, until their liquid evaporates and they brown.
  4. Stir the garlic, thyme, paprika and black pepper into the mushrooms and cook 1 minute. Add the soy sauce, stir, and take off the heat to cool for 5 minutes.
  5. In a bowl, roughly mash the lentils, then mix in the mushroom mixture, walnuts, egg and breadcrumbs. Shape into 4 patties about 3/4 inch thick.
  6. Wipe the skillet, heat the remaining half of the olive oil over medium heat and cook the patties 4 to 5 minutes per side until well browned and the centers reach 160°F (71°C).
  7. Toast the whole-wheat bread slices to use as buns.
  8. Build each burger on a toasted slice with romaine leaves, a patty, tomato slices and avocado, then top with a second slice.
