The Snow Covered the Grill: Grilled Skirt Steak Sandwich

Put the olive oil, red wine vinegar, Dijon mustard, garlic and thyme or oregano in a dish and mix to combine them using a fork. Put the meat on the dish and dredge it in the marinade to coat both sides. Let the meat marinate for at least one hour. Preheat the broiler or grill pan (or an outdoor grill). Cook the meat 2-3 minutes per side, then  cut into 2 equal pieces. Grill the cut side of the bread for a minute to toast the surface lightly. Slather the bread with the mayonnaise. Top with the meat, onion and tomato slices. Sprinkle with salt and pepper if needed. Makes 2 sandwiches
