Equipment

Ingredients

1 sweet potato
1 ½ tablespoons of ground coffee
1 tablespoon of sugar in the raw
¼ teaspoon of fennel seeds
¼ teaspoon of ground coriander
¼ teaspoon of coriander seeds
¼ teaspoon of cumin
¼ teaspoon of thyme
2 portobello mushrooms
½ of an onion (sliced thinly for a sandwich)
½ cup of avocado pesto
1 avocado
4 sandwich rolls (or your favorite bread)

Instructions

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 them and get them a little moist. Liberally rub the spice mixture on both sides of the mushroom. Add the spice rub 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.
Toast bread, if desired. Assemble the sandwiches and enjoy!

Notes

Don't rinse your mushrooms! Mushrooms are incredibly water absorbent and and will absorb a lot of that excess moisture. Instead, simply wipe the mushroom tops and gill side lightly with a damp paper towel to remove any excess dirt.

Toast the bread. In addition to preventing the portobello sandwich from becoming soggy, toasting the bread adds flavor, texture, and an amazing hearty crunch that contrasts the tender sweet potato and juicy portobello.

Coat the mushrooms well. After preparing the coffee rub, generously season the mushrooms on both sides for the best flavor. If you find the coffee rub is having trouble sticking to the top of the mushrooms, you can lightly rub the mushrooms with olive oil before coating.
