Halve the tortillas. Place a small bowl (in which you will add the dipping sauce after baking) in the center of a baking sheet lined with parchment paper.
Shred the cooked chicken into small pieces and place in a bowl with the cheddar, mozzarella, bell pepper, sweetcorn, tomato sauce and barbecue seasoning. Mix together until smooth.
Spread the filling over the halved tortilla and roll it up like a cone shape. Place the rolled tortilla with the narrow side against the bowl and go around like that. Then stack the second layer of tortillas on top. Continue until the filling is used up. You may have one to half a tortilla left over. Sprinkle some extra grated cheese over the wreath.
Remove the small dipping bowl from the baking tray and place the quesadilla ring in an oven preheated to 180 °C/350˚F (conventional oven) for 15-20 minutes. In the meantime, prepare the tomato salsa.
Place the ring on a wooden board or large plate and place your bowl of salsa in the center. Serve immediately.
