  • Servings 4
  • Ingredients 9


  • 2 tablespoons vegetable oil
  • 1 large red onion, halved and sliced
  • 5 large portobello mushrooms, halved and sliced
  • 2 tablespoons Old El Paso™ Garlic & Paprika Seasoning Mix for Tacos
  • 2 tablespoons water
  • 8 Old El Paso™ Super Soft Flour Tortillas, warmed following pack instructions
  • 50g feta cheese, crumbled

  • Heat half the oil in a large non-stick frying pan over a medium heat. Add the onion and cook for 3-4 minutes until softened.
  • Add the rest of the oil and the mushrooms to the pan, raise the heat and cook, stirring frequently, for 3-4 minutes until tender and browned.
  • Reduce the heat to low and stir in the taco seasoning mix and water. Cook gently for about 5 minutes, stirring occasionally. Meanwhile warm the tortillas as directed on the packaging.
  • Divide the mushroom mixture between the warmed tortillas and top with crumbled feta. Fold and serve with guacamole and soured cream.


  • Add extra protein to this dish by stirring in 100g tinned black beans or red kidney beans with the taco seasoning and water.
  • Use a mix of different mushrooms, if liked. Why not try sliced chestnut and shiitake with some halved button mushrooms.
