There's nothing better than a good old-fashioned Roast Beef Sandwich topped with olives and some Horseradish.

I'm going to assume most of you know about green olives but the kalamata olives might be a different story.

These Greek olives are only grown in Greece near the town of Kalamata (hence their name) so they can be a little pricey. They are high in sodium, and healthy fats and contain a natural antioxidant.

💭 Ingredient Substitution

Probably the closest substitute for kalamata olives would be French Black Olives or Gaeta Olives but if you can't find those either you can use regular California Black Olives but the dish will not be as good as Kalamata Olives.

If you don't have any honey mustard on hand you can easily make your own by making my Copycat Wendy's Honey Mustard Dipping Sauce.

Additionally, you can make your own Horseradish Sauce by following my Homemade Creamy Horseradish Sauce.

Or you can get really creative and use my Spicy Horseradish Mustard.

I like to use hoagie rolls when making sandwiches like this but you can pretty much use any kind you want.

I do however recommend you use bread that is soft on the inside but crusty on the outside. Bolillo buns or French bread would be my 2 picks for a substitute.

📋 Gather your Ingredients

You will need the following ingredients to make this Roast Beef Sandwich with Olives recipe (see recipe card for quantities): Hoagie Rolls, Honey Mustard, Horseradish Sauce, Roast Beef slices, Swiss Cheese slices, Kalamata Olives and Green Olives.
