  • Mixing Bowl
  • Large Skillet



  • 2 Tablespoons Butter
  • 6 cups Shiitake Mushrooms, sliced or chopped (sub any type of mushrooms)
  • 1 Tablespoon Cooking Oil
  • 2 cups Corn Kernels (fresh or defrost if using frozen)
  • 12 small Fajita-Sized Tortillas (I like to use flour tortillas for these, but use gluten-free corn tortillas if needed)
  • 3/4 cup Crumbled Cotija Cheese (can substitute feta)
  • Cilantro Leaves, for garnish


  • 2 Avocados
  • 1 Tablespoon finely chopped Cilantro
  • 1 Tablespoon finely diced Shallots
  • 1-3 teaspoons Fresh Lime Juice
  • 1/2 teaspoon Kosher Salt


  • Mash avocados with cilantro, shallots, lime juice (start on the low end of the range), and salt. Add more lime juice and / or salt to taste. If you’d like it spicy, stir in some hot sauce. Set aside.
  • Heat butter in large skillet over medium-high heat until melted. Add mushrooms and saute until very tender, 5 to 7 minutes. Season with some salt. Transfer cooked mushrooms to a bowl and return skillet to heat.
  • To heated skillet, add oil and then corn. Cook corn, without stirring, until it begins to pop and char on the bottom, 4 to 5 minutes. Stir and continue to cook until corn is very tender, about 2 minutes more. Season with some salt. Transfer to bowl with the corn.
  • Heat tortillas according to package directions (If you have a gas stove, you can lightly toast them over the gas or just heat them all in the microwave).
  • Spread tortillas with guacamole. Fill with mushroom-corn mixture and cotija. Garnish with cilantro leaves.
