- For the sauce, heat a medium sized saucepan over medium heat and add a drizzle of oil. Once hot, add the onion and cook until onion is soft, about 5 minutes. 
- Add the garlic, oregano and spices, stir into the onion and cook for about 30 seconds. 
- Add the passata, sugar and vinegar. Season with salt & pepper then reduce heat to medium low and cook for about 20 minutes, until slightly thickened. Remove from heat then blend until smooth. 
- Pre-heat oven to 190°C / 170°C fan. 
- For the enchilada filling, heat a large frying pan over medium high heat with a drizzle of oil. Add the onion and cook until just tender, about 3 minutes. 
- Push the onion to one side of the pan and add the chicken with a drizzle of oil. Cook until lightly golden. 
- Add the sliced peppers, garlic and chilli, stir well to combine then cook for about 4 minutes until peppers are just going tender. 
- Add half of the enchilada sauce along with the red kidney beans. Season to taste and cook for another minute or so.  
- Lay the flour tortillas on a clean work surface then divide the chicken mixture evenly between them. Roll each one up around the filling then arrange side-by-side in a large ovenproof dish (about 20x30cm). 
- Spoon remaining enchilada sauce over the top, spreading it out slightly with the back of a spoon, then sprinkle with cheese. 
- Bake for about 20 minutes, until cheese is melted and golden brown. 
- Garnish with chopped coriander and, optional, slices of red chilli. Serve with sour cream and lime wedges.
