Ingredients
1/4 cup olive oil
1/4 cup balsamic vinegar
1 teaspoon Dijon mustard
2 whole boneless, skinless chicken breasts, trimmed of fat
Salt and freshly ground black pepper
8 strips thick-cut bacon
12 slices brioche, or challah
1 ripe avocado
Juice of 1/2 lemon
1/3 cup homemade mayonnaise, or prepared
1 head green-leaf lettuce
1 tomato, thinly sliced
1/2 pound blue cheese, crumbled
Preparation
Combine oil, vinegar, and mustard in a small bowl. Season chicken with salt and pepper, and place in the bowl, stirring to coat. Marinate, covered, for at least a half an hour.
Preheat a grill or a grill pan to medium hot. Grill chicken until cooked through, 7 minutes on each side. Let cool slightly; slice thinly at an angle.
In a large heavy skillet over medium heat, cook bacon until crisp, and drain on paper towels. Toast bread under a broiler until lightly golden on both sides. Quarter and thinly slice avocado, and drizzle with lemon juice to prevent discoloration.
Assemble the sandwich in this order: bread, mayonnaise, lettuce, tomato, avocado, bread, mayonnaise, chicken, bacon, cheese, mayonnaise, bread. Serve immediately.
