Steps
  1. 1**Prepare the Herb Sauce:** In a small bowl or food processor, combine the fresh herbs, minced garlic, olive oil, lemon juice or vinegar, Dijon mustard (if using), salt, pepper, and red pepper flakes (if using).
  2. 2**Blend or Mince:** If using a food processor, pulse until the herbs are finely chopped and the sauce is well combined. If doing it by hand, finely mince the herbs and garlic, then whisk everything together in a bowl.
  3. 3**Adjust Seasoning:** Taste the sauce and adjust salt, pepper, or acidity as needed. You want a bright, flavorful sauce.
  4. 4**Warm the Steak:** Gently warm the sliced flank steak. You can do this by quickly searing it in a hot pan for about 30 seconds per side, or by placing it on a preheated grill for a minute or two. Avoid overcooking.
  5. 5**Serve:** Arrange the warmed flank steak slices on a plate and generously spoon the herb sauce over the top.
