Instructions

• In a large skillet over medium heat on the stove, fry the bacon until crisp, 8 to 10 minutes, turning occasionally. Transfer to paper towels to drain and let cool. Finely chop the bacon. In a small bowl and using a fork, combine all of the butter ingredients, including ¼ teaspoon of salt and ½ teaspoon of pepper, until well blended.
• Put the potatoes in a large saucepan of cold, generously salted water and bring to a boil over medium–high heat on the stove. Boil until the potatoes are tender when pierced with a fork, 12 to 15 minutes. Using a slotted spoon, remove the potatoes from the water and place on a baking sheet. Add the green beans to the boiling water and cook just until crisp-tender, 3 minutes. Drain in a colander and rinse with cold water to stop them from cooking.
• In a large serving bowl whisk the shallot, vinegar, tarragon and mustard. Add the oil in a steady stream, whisking constantly to emulsify. Season with ½ teaspoon of salt and ¼ teaspoon of pepper. Cut the warm potatoes lengthwise in half, add them to the bowl with the dressing and toss gently to coat. Add the green beans and tomatoes and toss gently again. Season with additional salt and pepper, if desired. Let stand at room temperature while preparing the steaks. (The salad can be prepared up to 4 hours ahead, kept covered in the refrigerator. Let stand at room temperature for 30 minutes to 1 hour before serving.)
• Prepare the grill for direct cooking over high heat (230°C to 290°C). If you’re using a charcoal grill, keep a small part of the charcoal grate clear of briquettes as a safety zone of indirect heat. Allow the steaks to stand at room temperature for 15 to 30 minutes before grilling.

• Lightly coat the steaks on both sides with the oil and season evenly with ½ teaspoon of salt and ½ teaspoon of pepper. Brush the cooking grates clean. Grill the steaks over direct high heat, with the lid closed, until cooked to your desired doneness, 6 to 8 minutes for medium rare, turning once or twice (if flare-ups occur, move the steaks temporarily over indirect heat). Remove from the grill and let rest for 3 to 5 minutes.
