Makes 4 sandwiches
1 lb. lean ground beef
2/3 c. crumbled feta or blue cheese
1/2 c. bread crumbs
1 egg, beaten
1/2 t. salt
1/4 t. pepper
4 to 6 cherry tomatoes, halved
4 hamburger buns, split
Mix together all ingredients except buns; form into 4 burgers. Grill over high heat to desired doneness, flipping to cook on both sides. Serve on buns.
For thick burgers that cook up more quickly and evenly, press your thumb into the center of each patty to form a dime-size hole. The hole will close as the burgers brown.
