Heat oil in a frying pan to a high heat and add the sliced onion. Cook until soft.
Lower the heat and add the diced chicken breast. Cook for about 5 minutes, until chicken is cooked through.
Add the tomato passata and the Tabasco® Chipotle sauce. Heat through to allow the tomato mixture to coat all the chicken.
To make the guacamole, combine onions, lime juice and Tabasco® Green Sauce in a medium bowl and mash gently with a fork to release the flavour of the onions. Add avocado and continue to mash until chunky; add salt and pepper to taste. Cover and refrigerate 1 hour to blend flavours.
For each serving, add the chicken mixture to the tortillas, and add your preferred amounts of salsa, guacamole, sour cream and cheese. We recommend about a heaped tablespoon of each.Recipe courtesy of Tabasco®
