Portobello Buffalo Burgers with Celery Apple Slaw

Ingredients for Portobello Buffalo Burgers with Celery Apple Slaw

• 1 medium onion, chopped

• 275g portobello mushrooms, trimmed and quartered

• 2 tablespoons plus 2 teaspoons olive oil, divided

• 450g ground buffalo

• 2 celery ribs

• 1/2 Granny Smith apple, cored (left unpeeled)

• 1 tablespoon mayonnaise

• 1 1/2 teaspoons cider vinegar

• 1 teaspoon olive oil

• 1 teaspoon whole-grain mustard

• Rounded 1/4 teaspoons sugar

• Equipment: an adjustable-blade slicer fitted with 1/8-inch julienne blade

• Accompaniment: 4 hamburger buns or kaiser rolls, split and toasted

Pulse onion and mushrooms in a food processor until finely chopped. Heat 2 tablespoons oil in a 10-inch heavy skillet over medium heat until it shimmers. Add mushroom mixture, 3/4 teaspoons salt, and rounded 1/4 teaspoons pepper and cook, stirring occasionally, until vegetables begin to brown and liquid has evaporated, 8 to 10 minutes. Transfer to a bowl and cool to warm, stirring occasionally, about 15 minutes.

Cut celery and apple into 2-inch-long thin julienne with slicer.

Whisk together mayonnaise, vinegar, oil, mustard, sugar, rounded 1/8 teaspoons salt, and 1/8 teaspoons pepper in a medium bowl. Add celery and apple, tossing to coat. Let stand 15 minutes to develop flavours.

Mix buffalo into cooled mushroom mixture with your hands until well combined. Form into 4 (4-inch) patties.

Heat remaining 2 teaspoons oil in a 12-inch heavy skillet over medium-high heat until it shimmers. Cook burgers, turning once, about 8 minutes total for medium-rare.

Serve burgers, topped with slaw, on buns.
