Make the Whipped Feta: Blend all the ingredients together in a small food processor until it incorporates into a thick and spreadable texture with flecks of feta.
Mix the Burgers: In a medium bowl, mix the burger ingredients together. Form into 4-5 patties.
Cook the Burgers: Heat a small bit of oil in a large nonstick skillet over medium high heat. Add burgers and cook for 3-4 minutes per side, until golden brown and the inside of the burgers is fully cooked (165 degrees).
Brush with Butter: As the burgers are finishing cooking, brush the outside with the melted butter and hot sauce mixture.
Finish: Arrange your burgers on buns with lettuce and a shmear of the whipped feta. SO GOOD.
