Grate onion and garlic. Core and slice pears. Also, replace the bacon and ground beef with black bean patties for vegetarians.

In a large bowl combine, ground beef, grated onion, garlic, salt, pepper and worcestershire sauce. Do not over mix.

In a large non-stick skillet, cook bacon. Drain on paper towels. Remove all but one teaspoon of bacon grease.

Melt butter over a medium-high heat, swirl pan until butter browns. Add in pears, brown sugar, salt and a pinch of red pepper flakes. Cook, until just softened, about 3-4 minutes. Set aside.

Heat a gril pan over a medium high heat. Form beef mixture into four patties. Drizzle buns with olive oil and grill until slightly toasted. Slather with a little bit of mayo.

Grill burgers until desired doneness, about 2-3 minutes per side for medium. When the burgers are almost done cooking top with brie and pour two tablespoons of water into the pan, cover until cheese is melted, about 30 seconds.

Top the bottom of each bun with a handful of arugula, then the patty, followed by bacon and pears.
