  • 16 ounces mushrooms sliced into quarter-inch slices
  • 1 bunch asparagus woody ends snapped off
  • 3 bell peppers (green, yellow, and red) cut in strips
  • 1 red onion sliced
  • 2 Tablespoons olive oil
  • 2 teaspoons chili powder
  • 1 teaspoon paprika
  • 1 teaspoon ground cumin
  • 1 teaspoon garlic powder
  • 1 teaspoon Mexican oregano (or any dried oregano)
  • salt and pepper to taste
  • tortillas warmed (for serving)
  • guacamole, salsa, vegan sour cream, etc. for serving (optional)


  • Preheat the oven to 450 degrees F. Line two large baking sheets with foil or parchment paper and set aside.
  • Place the vegetables in a large mixing bowl or casserole dish. Drizzle with the olive oil and toss well to coat.
  • In a small bowl, combine the chili powder, paprika, cumin, garlic powder, oregano, and salt and pepper. Mix the seasonings together, then add to the bowl of vegetables. Toss well to coat.
  • Divide the vegetables among the two lined sheet pans. Smooth out the vegetables so they are in a single layer as much as possible.
  • Place the pans in the oven to roast. Give the vegetables a stir after 15 minutes, then bake 5-10 minutes longer until tender and lightly browned.
  • Serve the roasted vegetables immediately with warmed tortillas and your favorite toppings. 


Leftovers can be stored refrigerated for several days and reheated.
