It is amazing that one of my favorite deli foods, the classic Reuben sandwich, takes just a few simple ingredients to prepare at home, and is hearty and filling.
Ingredients

Instructions
Step 1. Place 2 slices of rye bread on a plate. Spread prepared Thousand Island Dressing on one side of each piece.

Add a half-slice of Swiss cheese to each piece of bread. Top with thin slices of corned beef and a tablespoon or two of prepared sauerkraut.

Top with the second slice of bread.

Step 2. Heat extra virgin olive oil in a frying pan over medium-low heat. Add the sandwich to the hot pan. Heat until the bread is toasted to a golden brown. This takes about 3-5 minutes per side.

Step 3. Turn the Reuben sandwich and heat until toasted to a golden brown.
Ingredient Substitutions
- Pastrami or turkey for Corned Beef
