Break tempeh into small chunks and boil in “chicken” flavored vegetable broth for about 5 minutes, or until all liquid is absorbed. Set aside to cool while prepping other ingredients.
Prepare Tofu-Cashew Mayo by blending all ingredients in a high powered blender or food processor until smooth.
Add 3-4 tablespoons Tofu-Cashew Mayo to a small bowl and stir in dijon mustard, nutritional yeast, garlic powder, and lemon juice; set aside.
In a medium bowl, add celery, onion, sunflower seeds, cooled tempeh, and Tofu-Cashew Mayo sauce. Mix well and chill in the refrigerator until cold.
Serve on whole grain bread with lettuce, tomato, and broccoli microgreens. Enjoy!
