This recipe is well worth the time involved. I love using meaty portobellos as sandwich fillings.

  • 2 Portobello Mushrooms
  • ½ cup of avocado pesto
  • 1 Sweet Potato
  • 1 avocado
  • ½ of an onion (sliced thinly for a sandwich)
  • 4 Sandwich Rolls (or your favorite bread)
  • ¼ teaspoon of Fennel Seeds
  • ¼ teaspoon of ground coriander
  • ¼ teaspoon of coriander seeds
  • ¼ teaspoon of cumin
  • ¼ teaspoon of thyme
  • 1 ½ Tablespoons of ground coffee
  • 1 Tablespoon of sugar in the raw


  • Preheat oven to 375.
  • With a fork or knife, poke a few holes on the sweet potato. Cover with foil and bake for about 40 minutes. (or microwave for 7-10 minutes with no foil)
  • In a spice or coffee grinder, add the coffee and spices. Grind until a fine powder. Using a wet cloth, wipe down the mushrooms to clean and get a little moist. Liberally rub the spice mixture on both sides of the mushroom. Add the spice run to the onions. Place on a parchment paper lined baking sheet and bake for 25 minutes.
  • Slice the tomato and avocado.
  • When the potato is tender, remove the foil and skin. Chop into ¼ inch round slices. Slice the mushroom on an angle. Assemble the sandwiches and enjoy!
