French Dip Sandwiches are one of Mike’s favorite meals. Something about dipping the almost rare beef into a steaming hot bowl of cheese covered soup that says comfort food. As I mentioned before, French Onion Soup is a very simple and quick soup to make – great for a weeknight dinner or elegant dinner party. French Dip Sandwiches 1 baguette 1 pound of roasted beef, sliced 1/2 pound of provolone cheese, sliced mayonaise dijon mustard Slice baguette down the side to create an opening. Fold open. On one side – the bottom side – and top with beef and cheese. Place on a baking sheet. Place under the broiler for 2-3 minutes until the cheese is melted and bubbly. Slather on mayo and dijon on the top half and fold together. Slice into four portions. I love to serve these with French Onion Soup. Here is the very quick and easy recipe!
