Season steak on both sides including the edges with Montréal Steak Spice and let it sit until it gets to room temperature, about 30 minutes.
In a skillet over high heat, add oil and when it gets hot, place the well-seasoned steak. Grill for 5 minutes on one side then flip it and grill until desired doneness.
When the meat is done, cover with foil forming a tent and allow it to rest 10 minutes while assembling the salad.
After 10 minutes, thinly slice the steak and evenly place them on one side of the bowls or plates on top of the salad. Add French fries on the other half and drizzle on Ranch dressing. Serve immediately.
