Po' Boy Sandwich

Vegan Culinary Experience by Chef Jason Wyrick

  • A side of French fries would make a tasty addition to this sandwich. Jason Wyrick

Serves 2

Gravy ingredients
1/2 yellow onion, sliced
1 teaspoon vegan margarine or olive oil
1 tablespoon flour
1 cup water (or the leftover flavoring liquid from the bake-and-simmer method if you are seasoning plain seitan)
1/4 teaspoon salt (omit or reduce if sodium is a concern)
1/2 teaspoon freshly ground black pepper
1 teaspoon fresh thyme leaves

Sandwich ingredients
2 cups of seitan, sliced (or 2 large portabellas, sliced)
1 cup shredded lettuce
1 large tomato, sliced
Creole mustard (or use Dijon mustard instead)
1/4 cup Vegenaise or Nayonaise (optional)
12- to 14-inch loaf French bread

Gravy preparation

Slice half a yellow onion as thin as you can.

Over medium high heat, sauté the onion in the margarine until it caramelizes (browns) thoroughly. Reduce the heat to medium and add the flour, stirring and cooking for about 2 minutes. Watch the flour to make sure it doesn't burn. Add the water and stir until the sauce thickens.

Add the salt, pepper, thyme, and optional ingredients; reduce the heat to medium-low, and cook this for about 5 minutes.

Sandwich assembly

Cut the French bread in half to make two sandwiches. Cut each of the halves enough to fold the bread open, without slicing all the way through.

Fill the bread with the seitan, optional mayo, Creole mustard (or Dijon mustard), and gravy; then top each sandwich with the shredded lettuce and sliced tomato. Serve immediately.


  • Optional: add 2 tablespoons red wine or 1 tablespoon of beef-style vegetarian bouillon to the water when making the gravy.
  • If you are using store‐bought seitan, Trader Joe's Beefless Strips are perfect for this sandwich.
  • If you are using plain seitain, try the bake-and-simmer method to add a more authentic flavor. Combine the seitan plus the following ingredients in a small baking dish:
         1/4 onion, chopped
         1 stalk celery, sliced
         1/2 green bell pepper, chopped
         6 cloves garlic
         1/2 teaspoon salt
         1/2 teaspoon black pepper
         1/2 teaspoon cayenne
         1/2 teaspoon dry mustard
         Enough water to cover
    Give everything a stir, cover the dish, and bake it at 350 F (177 C) for about 1 hour. Remove the seitan from the liquid and veggies, and proceed with the sandwich assembly.
