Preheat the oven to 400°F. Line a baking sheet with aluminum foil. This will be used to finish cooking your steaks in the oven.
Preheat a large skillet to medium-high heat (7-8 on the dial). Add one tablespoon of oil to the hot pan.
Place each steak into the pan and sear (cook) for 2 minutes. Carefully flip the steak over and cook for another 2 minutes.
Move the pan off the burner and turn it off.
Move each steak to the foil-lined baking sheet. Top each steak with ½ tablespoon of Montreal steak spice and 1 tablespoon of BBQ sauce. Use the back of a spoon to spread the spice and sauce over each steak.
Place the baking sheet in the oven and cook the steaks for 7-12 minutes to the desired doneness. The longer that you cook the steak, the closer it will get to being well-done (no pink left in the center of the steak). If you like a rarer steak, cook in the oven for a shorter time (center of steak will remain red-pink).
Remove the steak from the oven and cover loosely with a piece of aluminum foil to keep it warm, 3-5 minutes.
Prepare the caesar salad according to the package directions.
