We'll start by making the burgers. First combine all of your burger ingredients but the feta and ghee in a bowl, using your hands to mix well before diving into 4 parts. Flatten each until they are roughly 1/2-inch thick. In the middle of each patty, place 1/4th of your feta, folding the patty over the cheese. Press down to seal, shaping your patty so the feta is sealed in the center. Cook in a hot pan greased with the ghee over medium-high heat, roughly 5-6 minutes each side. Once done, set aside where they can stay warm but will not keep cooking.

Meanwhile, prepare your salad. Place all of the salad vegetables in a bowl, adding the crumbled feta, olives, capers, and oregano, before drizzling with olive oil and serving with your feta burgers.
