Step 1

In a food processor, combine the cooked lentils, shallots, carrot, garlic, tomato paste, Worcestershire sauce, cumin, coriander, salt and pepper. Pulse until the mixture is mostly smooth, with a few chunks for texture.

Step 2

Add the oats and pulse briefly to combine. The mixture should be thick enough to hold its shape when formed into patties. If it's too wet, add more oats, a little at a time, until it reaches the right consistency.

Step 3

Using your hands, shape the mixture into 4 patties about 3-4 inches wide and ½-inch thick.

Step 4

Heat the olive oil in a large skillet over medium heat. Cook the burgers for 4-5 minutes on each side, until they are golden brown and crisp on the outside. Serve the lentil burgers on buns with the burger sauce, if desired, and your favorite toppings.
