  • Small pot
  • Wide pot
  • Food processor


Sweet and spicy mushrooms:

  • 1 tablespoon neutral oil
  • 1 shallot peeled and sliced into thin wedges
  • pounds king trumpet mushrooms shredded; or use any variety mixed mushrooms and mince them
  • 6 cloves garlic peeled and minced
  • 2 peaches
  • 1 large tomato cored and diced
  • 15 ounce can black beans drained and rinsed
  • 7 ounce can chipotles in adobo sauce see note
  • 1 cup water or vegetable stock
  • Salt and pepper to taste

Brussels sprouts slaw:

  • 12 ounces Brussels sprouts trimmed and shredded
  • ¼ cup mayonnaise
  • 1 teaspoon maple syrup plus more, if desired
  • 1 lime juiced
  • ½ teaspoon chili powder
  • Flaky sea salt to taste
  • A few splashes of water as necessary

For serving:

  • 8 4-inch corn tortillas
  • Cooking spray or oil
  • Crumbled or shredded cheese
  • Fresh cilantro roughly chopped


Cook the shallot:

  • Heat oil in a wide pot over medium high heat. Add the shallot and cook for 4-5 minutes until it begins to soften.

Cook the mushrooms:

  • Add the shredded mushrooms and cook stirring often, for 8-10 minutes until they begin to crisp up and turn golden brown around the edges. Season with salt and pepper.
  • Add the garlic to the pot and cook for 1 minute until fragrant.

Blanch the peaches:

  • While the mushrooms cook bring a small pot of water to a boil. Add the peaches and boil them for 2-3 minutes until they begin to soften. Drain and transfer to an ice bath for 5 minutes. Remove the skins, cut the peaches in half, and remove the pits. Dice the peaches and set aside.

Prepare the chipotles in adobo sauce:

  • Add as many of the chipotles in adobo sauce as you like to a food processor and pulse until blended. Set aside.

Cook the tomatoes and peaches:

  • Add the diced tomato and peaches to the pot and season with salt and pepper. Cook for 5 minutes until they soften. Add the black beans and chipotles in adobo sauce and cook until the ingredients begin to bubble in the pot.

Simmer the mushrooms:

  • Pour in 1 cup of water or stock and bring to a boil. Reduce heat and simmer for 30 minutes until reduced and thickened. If too much liquid evaporates too quickly add a splash of water as necessary to loosen up the mushrooms. Taste and season with salt and pepper.

Prepare the Brussels sprouts slaw:

  • In a bowl whisk together the mayonnaise, lime juice, maple syrup, and chili powder until smooth. Taste and season with flaky sea salt. Add a splash or two of water to thin out the dressing. Add the Brussels sprouts and toss to coat. Refrigerate until needed.

Prepare the baked tostada shells:

  • Preheat oven to 400ºF.
  • Lightly brush corn tortillas with oil or spray with cooking oil and arrange in an even layer on two baking sheets (4 per baking sheet).
  • Transfer to the oven and bake for 5-6 minutes per side or until the tortillas are crispy. Remove from the oven and immediately sprinkle with salt.

To serve:

  • Place two tostada shells on each plate and pile the mushrooms on top. Spoon the Brussels sprouts slaw on to each tostada and garnish with cheese and cilantro. Enjoy!


Note: use as many of the chipotles in adobo sauce as you like, depending on your heat tolerance. I used an entire can which resulted in a spicy finished product!
