Combine all ingredients thoroughly in a mixing bowl and ideally allow to marinate for at least 45 minutes to an hour before cooking. For me, the best way to get all the meat evenly seasoned is to get in there with your hands, and mix and massage to distribute all the seasonings on and between all the slices of meat.
PAN FRY OR SAUTE METHOD: Cook the meat in four separate batches on an oiled (about 1.5 teaspoons per batch) pan preheated to medium high, for 2.5 to 3 minutes, stirring occasionally to ensure all pieces are cooked. If you, like I, love onions, you can saute some 1/4" thick pieces of sliced onions with each batch.
OVEN METHOD: Preheat the oven to 425F. Mix and additional 1.5 to 2 Tablespoons oil in with the meat and spread it evenly in a single layer on a foil-lined sheet pan or broiler pan. Place the pan about 4 inches under the heat element (usually the second rack in your oven) and cook for 15 minutes.
GRILL METHOD: You'll need a grill basket/fine grate to keep the meat from falling through the slats. Spread the meat in a single layer and cook over medium high heat (and at least 5 inches above the coals or gas element) until the meat is cooked 4 to 6 minutes per side, depending on the thickness of the cut and grill heat.
