Bring raspberry balsamic to a boil and add onions. Leave to simmer until onions cook down or approximately 2 minutes.
in a large bowl combine the ground meat, onion, carrot and Bloody Good on Everything (making sure to not over mix the meat). Form into 8 patties, making a depression in the center of each. Cook on the grill over medium high heat 3-4 minutes on each side until the internal temperature reaches 160 degrees F. Add the cheese just before removing the patties and allow to melt. Toast the bun and place the burger, pickled onions, bacon and avocado slices, then top with the top bun.
*For low carb version, omit the bun
