Preheat the oven to 425°F (to roast the cauliflower). Start prepping when the oven comes up to temperature!


Wash or dry all produce.* Mince or grate the garlic. On a baking sheet, toss the cauliflower with a drizzle of oil. Season with salt and pepper. Roast in the centre of the oven, stirring halfway through cooking, until golden-brown, 28-30 min


Meanwhile, heat a medium non-stick pan over medium heat. Add the panko. Cook, stirring often, until toasted, 2-3 min. Transfer to a medium bowl.


Add a drizzle of oil to the same pan, then the onions. Cook, stirring occasionally, until softened, 4-5 min. Reduce the heat to low, then add 1 tsp sugar (double for 4 people) and 1/2 bottle vinegar (1 bottle for 4 people). Cook, stirring occasionally, until the onion is dark golden and sticky, 18-20 min.


Meanwhile, in another medium bowl, combine the ground beef, oregano and half the garlic. Season with salt and pepper. Form the beef mixture into two 5-inch wide burger patties (4 patties for 4 people). Heat a large non-stick pan over medium-high heat. Add a drizzle of oil, then the burgers. Pan-fry the burgers until cooked through, 3-5 min per side.


Meanwhile, in another medium bowl, stir together the mayonnaise and remaining garlic. Season with salt and pepper. Split the buns and spread the bottom halves with half the aioli. When the cauliflower is finished roasting, toss them with the remaining aioli.


Top each bun with a burger patty and onions. Toss the mayo-coated cauliflower with the panko. Serve the burgers with the cauliflower on the side.
