1 1/3 pounds ground sirloin
1 tablespoon Worcestershire
1 shallot or small onion minced
1/2 pound crumbled blue cheese
Extra-virgin olive oil, for pan
McCormick's Montreal Seasoning
Combine first 3 ingredients and divide meat into 4 equal amounts. When forming each patty, nestle a pile of blue cheese crumbles into the center of the meat, and gently form patty around cheese.
Brush or drizzle burgers with extra-virgin olive oil and grill (I use a grill pan) 7 to 8 minutes on each side.
Also good with bacon and cheddar as the filling. Just crumble 6-7 slices of bacon and mix with crumbled cheddar instead of blue cheese.
