Roast Beef Sandwich with Wasabi Mayo

Wasabi mayo gives these roast beef sandwiches a delightful zing.

12 ounces roast beef, sliced

4 ounces hot pepper jack cheese, sliced thin

8 slices sourdough bread

4 lettuce leaves

1 tomato, sliced

1/4 red onion, sliced

1/2 cup mayonnaise

1 tablespoon wasabi powder

2 teaspoons water

1 teaspoon tamari

Pinch of salt

Ground black pepper to taste

Garlic powder to taste


  1. In a small bowl, mix the wasabi powder and water together until well blended. Whisk in the mayo, tamari, salt, pepper and garlic powder. Set aside for a few minutes to let the flavors blend.
  2. To assemble the sandwiches, spread 1 tablespoon of wasabi mayonnaise on each slice of bread, then top 4 bread slices with 3 ounces of roast beef, sliced cheese, 1 lettuce leaf, tomato and onion slices and a second slice of bread.

Serving Suggestion

Brown-bagging it? Make the wasabi mayo the night before. Leftover wasabi mayo can be kept in the refrigerator for up to 5 days; use it to spice up a tuna or chicken salad.
