In a bowl combine ground turkey, minced fresh rosemary, minced garlic, 1.5 teaspoons of salt, black pepper and red pepper flakes. Mix until just combined.
Using a 1/4 cup measuring cup, scoop out the turkey mix and then flatten into 1/2" thick patties.
Heat a large skillet over medium high heat with 2tbsp of avocado oil
Working in batches, fry each patty for about 5-7 minutes on each side, until golden brown and internal temperature reaches 155.
Remove from heat and cover with foil for 5 minutes so internal temperature can reach 165.
Assemble by smearing the gorgonzola mayo on the slider bun, top with a turkey patty, caramelized onions and fresh arugula. Enjoy!
