Preheat your grill or grill pan to medium-high heat.

In a large bowl, combine the ground turkey, Dijon mustard, minced rosemary, minced thyme, salt, and black pepper. Gently mix until the ingredients are evenly distributed.

Divide the mixture into four equal portions and shape them into patties.

Brush each patty with olive oil to prevent sticking on the grill.

Grill the turkey burgers for approximately 7-8 minutes per side or until they reach an internal temperature of 165°F (74°C).

Assemble the burgers on toasted buns, adding your favorite toppings and condiments.
