Place the fillet tips in a shallow non-reactive dish. Combine the red wine vinegar, red wine, 1/4 cup of the olive oil, Worcestershire, garlic, shallots, Essence, soy sauce, mustard and black pepper in a non-reactive mixing bowl and whisk to combine. Pour marinade over the meat, stirring to coat the meat well with the marinade. Cover with plastic wrap and refrigerate for at least 1 hour and up to overnight, turning meat occasionally.

Preheat the oven to 400 degrees F. Place the bread slices on a baking sheet and lightly brush both sides with the remaining 1/4 cup of olive oil. Sprinkle with Essence. Bake for 8 minutes, or until light golden brown. Remove from the oven and allow to cool. Set aside.

Preheat a broiler to high. Thread the marinated meat cubes onto skewers, dividing the meat evenly. Broil the skewers about 4 inches from the heat, until the meat is cooked to your liking, about 4 to 5 minutes for medium-rare. Remove from the broiler and set aside on a plate while you assemble the salads.

Place the lettuce in a large bowl and toss with the dressing to taste. Divide the salad among 6 large salad plates and top each plate with 1 of the skewers . Garnish each salad with 2 croutons and top with shaved Parmesan. Serve immediately.

Bring a small saucepan of water to a boil. Crack the eggs into the water and cook for 30 seconds. Drain.

Combine the anchovies, garlic, salt, and pepper in a small bowl and mash to a paste with a fork. Break the egg into the mixture and whisk to blend. Add the cheese, lemon juice, and mustard and whisk well. Add the olive oil in a steady stream, whisking constantly to form a thick emulsion. Add the Worcestershire and pepper sauces and whisk well to combine. Cover tightly and refrigerate until ready to use. (The dressing will keep refrigerated for up to 1 day.)
