DIRECTIONS

To prepare salsa: Grill grapes, onion, and jalapeño pepper in a grill basket over medium high heat for 10 minutes (or broil on a foil-lined baking sheet) until lightly charred, stirring occasionally. Let cool, then place in a food processor with cilantro, lime juice, and garlic. Process until all ingredients are finely chopped.

To prepare burgers: Place lentils, rice, walnuts, onion, breadcrumbs, lime juice, chili powder, cumin, beans, and eggs in a food processor. Pulse until all ingredients are coarsely chopped with some small pieces still visible, scraping down the sides and moving the mixture from the bottom of the bowl to the top to blend evenly. Using wet or lightly oiled hands, shape into 8 patties. If mixture is too soft, freeze briefly to firm. Coat on both sides with olive oil spray and cook over medium heat in 2 skillets for 10 minutes, turning occasionally and coating with additional olive oil spray. Burgers should be nicely browned and cooked through. Place a little lettuce on bun bottoms and top with burgers, slices of avocado, and grape salsa.
