Directions

  1. Preheat the oven to 425°F.
  2. Wash and dry the produce as you prepare.
  3. Make a simple marinade by whisking oil, soy sauce, vinegar, maple syrup, paprika, and pepper in a small bowl.
  4. Trim the mushroom stems and scrape out the gills; place the caps on a baking sheet and coat them with the marinade, turning to cover evenly.
  5. Roast the mushrooms in the oven until tender, about 10–12 minutes; remove and set aside.
  6. Halve and pit the avocado, then scoop the flesh into the reserved bowl with the marinade.
  7. Add nutritional yeast, mayo, and spices to the avocado; mash until smooth to form the spread.
  8. Slice the tomato and coarsely grate the carrot; set aside with the arugula.
  9. Slice the mushrooms into strips.
  10. Toast the bread if desired.
  11. Spread the avocado mayo on all bread slices; layer with mushrooms, tomato, carrot, and arugula, then cap with the remaining slices.
  12. Transfer the assembled sandwiches to plates and serve.

Two tips

  • Make the avocado-mayo spread in advance and refrigerate for up to a day for quicker assembly.
  • If you like extra greens, swap in more arugula or add another tomato slice to the stack.
