These Feta-Stuffed Hamburgers are a delicious and easy way to show off your culinary skills! Packed with flavor, they'll be sure to impress your friends and family. Best of all, they're surprisingly simple to make. So fire up the grill and get cooking!
Preheat an outdoor grill for medium heat, and lightly oil the grate.
Knead together the ground beef, Worcestershire sauce, parsley, salt, and pepper in a bowl. Form the mixture into 8 equal-sized balls; flatten to make thin patties. Place about 1/4 cup of feta cheese onto each of four of the patties. Top each of the patties with cheese with one of the patties without; press the edges together to seal the cheese into the center.
Cook on the preheated grill until the burgers are cooked to your desired degree of doneness, 7 to 8 minutes per side for well done. An instant-read thermometer inserted into the center should read 160 degrees F (70 degrees C).
