Ingredients

  • Tempeh

  • 4 oz tempeh, thinly sliced
  • ¼ cup soy sauce
  • ¼ tsp garlic powder
  • ¼ tsp fresh black pepper
  • Black Pepper Tahini

  • 2 tbsp tahini
  • 1 tbsp soy sauce
  • ½ tsp fresh black pepper
  • 1 tsp white miso paste
  • 1 clove garlic, finely grated
  • Sandwiches

  • 1 tbsp olive oil
  • ½ yellow onion, thinly sliced
  • 6 oz baby bella mushrooms, sliced
  • 1 cup arugula
  • 2 servings ciabatta bread

Preparation

Marinate Tempeh

In a resealable bag or container, whisk together soy sauce, garlic powder, and black pepper. Add the sliced tempeh, tossing well to coat and allow it to marinate for at least 4 hours, or preferably overnight.

Prepare Tahini Sauce

In a small bowl whisk together tahini, soy sauce, black pepper, miso, and garlic. Thin with water as needed until a mayo-like consistency is achieved.

Cook Tempeh

Heat a small drizzle of olive oil in a medium non-stick pan over medium heat. Add the marinated tempeh, allowing it to cook for about 3 minutes or until golden brown. Flip and allow it to cook for another 3 minutes.

Sauté Mushrooms & Onions

Heat 1 tbsp olive oil in a pan over medium-low heat. Add the onions, sauteing for about 10 minutes until they begin to caramelize. Add the mushrooms, cooking until they release their liquid and pan begins to dry, about 8 minutes. Season with salt and a generous amount of black pepper to taste before removing from heat.

Assemble

To assemble, spread a generous amount of tahini sauce on each ciabatta, add tempeh, top with mushrooms and onions, and finish with a handful of arugula.
