2. Remove the steak and onions from the marinade and brush lightly with oil and season with salt and pepper. Heat indoor grill over high heat until very hot. place steak and onions on the grill and Cook until the steak and onions have browned nicely, about 6 to 8 minutes, then flip and continue to cook until the other side is browned and the meat is done to your liking, about another 5-6 minutes for medium rare. Remove from the grill, shave a thin layer of Boursin on the top of the steak and onions and let rest for 5 to 10 minutes.
3. Brush bread slices lightly with oil and place on the grill until nicely toasted, about 1 to 2 minutes. Spread a layer of Boursin on both sides of the bread. Slice the steak into long 1/4 inch slices against the grain. Place a handful of arugula on the bottom piece of bread, then top with steak and onions and serve.
