METHOD

For the Mushroom Blend:
Heat oven to 400°F. To a food processor fi tted with a grater, grate mushrooms. Transfer  mixture to a bowl and toss with the coriander, fenugreek, black pepper, garlic, and salt. Spread the mushroom mixture onto a parchment-lined sheet tray. Roast 8 minutes; cool slightly. To the food processor fitted with a blade, add mushroom mixture and cilantro; pulse to combine. Cool completely. 

For the Harissa Aïoli:
In food processor, combine yolks, Dijon, harissa, Tabasco, and lemon. While processing, stream in oil to emulsify. Season with salt, cover, and refrigerate.

For the Broccoli Slaw:
In a large bowl, combine vegetables, lemon, and ¼ cup Harissa Aïoli. Season with salt, cover, and refrigerate at least 20 minutes. 

To Assemble and Serve:
In a cast iron pan over high flame, heat a slick of oil. Form 4-ounce patties by combining equal parts ground beef and Mushroom Blend; season with salt and pepper. A few at a time, place patties in pan and sear on both sides, placing a slice of cheddar on top to melt and cooking to desired doneness. On the top half of buns, spread a smear of ketchup and add Broccoli Slaw to the bottom half of the bun. Place the patty on top, along with red onion, and top bun.
