Heat the oil, paprika and garlic in a frying pan, add the chicken and fry over a medium heat for 5 minutes until the chicken is cooked through. Remove from the pan, then wipe the pan clean with kitchen paper.
Place the tortillas on a board and cover one half of each tortilla with cheese, cooked chicken, jalapeño peppers and coriander. Fold each tortilla to enclose the filling.
Heat the frying pan until hot, add the tortilla sandwiches and cook for 2 minutes on each side, until crisp and the cheese starts to melt.
Serve the quesadillas, cut into wedges, with tomato salsa.
