Prepare the Soy Curls: Dissolve 1 tsp of vegan chicken bouillon powder in 2 cups of warm water. Soak the soy curls in this broth for 10 minutes or until soft. Once rehydrated, drain the soy curls and gently squeeze out excess liquid (save the broth).
Sauté the Soy Curls: Heat a non-stick skillet over medium heat. Add the soy curls to the skillet, with a little of the saved broth, and sauté them for 5-7 minutes, stirring occasionally. Add tamari (if using) to the soy curls during the sautéing process for extra flavor and 1/2 tsp of vegan chicken bouillon powder. Continue to sauté until the soy curls are slightly crispy onthe edges. Add some salt if needed.
Chop Ingredients: After sautéing the soy curls, remove them from the skillet and roughly chop them into bite-sized pieces. Then, dice the apple, celery, and shallot, and chop the walnuts (if using) to prepare for mixing.
Make the "Chicken" Salad: In a large mixing bowl, combine the sautéed soy curls, diced apple, celery, shallot, walnuts (if using), and dried cranberries. Then, add the vegan mayo, Dijon mustard, and lemon juice. Toss everything together until well combined. Enjoy!
Assemble the sandwich (optional): Lay out the slices of bread. Place a few lettuce leaves on one side of each sandwich. Spoon a generous portion of the soy curl salad onto the lettuce. Add slices of tomato and avocado, if using. Top with the other slice of bread.
Serve: Cut the sandwich in half and serve immediately.
