Directions:
Step 1: In a large mixing bowl, add all the ingredients for the patty aside from the olive oil and flour.
Step 2: Make 4 to 6 patties out of the mixture.
Step 3: Dip each patty into the flour and make sure to coat each evenly.
Step 4: Place a skillet on the stove and turn the heat to medium.
Step 5: Add the olive oil and allow it to become hot.
Step 6: Add the patties and cook both sides until the colour turns brown.
Step 7: Set aside the accumulated grease from the patties.
Step 8: Add the onions and 1 tablespoon of water. Cook until the onions caramelize.
Step 9: In a medium mixing bowl, add in the water, 1/4 cup of flour, beef broth, Worcestershire sauce, gravy master, seasoning salt, and pepper. Whisk until well mixed.
Step 10: Transfer the mixture into the skillet and stir until thick.
