Start by laying out all your ingredients on a clean surface. This will help streamline the assembly process. Think of it like putting on a show; your mise en place is your stage!
Thinly slice the tomatoes and chop the green onions. Remove the seeds from the tomatoes to prevent sogginess. Place these aside. Clean the iceberg lettuce leaves and pat them dry gently.
In a bowl, combine the mayonnaise and Dijon mustard. Stir this mixture well until it’s smooth. This creamy sensation will become the star supporting player in our performance.
Now comes the fun part. Take slices of bread (I prefer French or wheat) and spread the mayo-mustard mixture generously on both sides. Layer the turkey evenly, followed by provolone cheese, lettuce, tomatoes, green onions, and alfalfa sprouts. Be generous with each layer, creating a colorful and inviting look.
Once assembled, cut the sandwich in half or quarters to make it easier to eat. Serve it up with your favorite chips or a crisp pickle on the side, and enjoy!
