To make the sauce finely chop the onion and mushroom and gently fry in some olive oil. Once the onion is transparent add the paprika and boullion powder and the tomato paste. Cook gently and add salt if necessary.
Fry the chicken style strips until ready.
Turn both the sauce and the strips down to minimum while you cook the pancakes.
When each one is cooked fill with a layer of mayonnaise, then some of the sauce and lastly a couple of the chicken style strips. Wrap up and keep warm in the oven if you are cooking a large batch.
