1 lb ground beef
1 tsp salt
1 tsp black pepper
1 tsp garlic powder
1 tsp cayenne pepper
About ½ cup feta cheese
Mix spices into beef, using hands, until well-mixed.
Form 8 small balls of meat, then press into very flat pancake shapes.
Top four with about 2 tbsp crumbled feta cheese, then cover with the other four.
Press together firmly to flatten, then crimp edges tightly to make four burgers. Chill.
Cook as regular burgers in a skillet or on the grill. Handle gently to avoid crumbling.
Serve on toasted white or rye bread with spicy mustard.
