We grilled this for a segment on Trophy Quest Outdoors. It was so good that it stopped the filming while we all ate! This makes a great lunch or dinner menu. Flank steak is perfect for sliced steak. In our house...

Open Faced Steak Sandwich

 1.5 pound Flank Steak
 1/2 T Cavender's Greek Seasoning
 6 Pieces Thickly Sliced Crusty Bread
 1 Large Onion Sliced
 2 cups Sliced Mushrooms
 2 T Olive Oil

Bring flank steak to room temperature


Season with Cavender's on both sides.

Grilling Flank Steak:

Hot and fast for flank steak


8-10 minutes depending on thickness and heat


Grill temps 500-600F


Place steak on GrillGrates on a slight diagonal


Lift and Twist (1/2 twist) after 3 minutes


Turn steak at 5-6 minute mark depending on how hot you are grilling


Grill to finish. I shoot for internal temp of 120F in the thickest part knowing that it will raise slightly and the thinner parts will be less rare. Rest 5 minutes before slicing

Griddling Mushrooms & Onions:

The GrateGriddle is ideal to grill up the onions and mushrooms right along the the flank steak. Pour the 2T of olive oil on a hot GrateGriddle and add the mushrooms and onions. Sprinkle a little Cavender's and toss occasionally. Cook until the onions begin to caramelize.

Toast Bread Slices on the Grill

While the flank is resting, grill bread slices 1 min per side. Be careful not to blacken the bread.

Slicing Flank Steak:

Slice thin on a sharp bias against the grain

Build open faced sandwiches:

1 slice of bread per person.


Place 3-4 slices of steak on the toasted bread and top with mushrooms and onions


Bon Appetit!
