Heat oven to 220C/200C fan/gas 7.
Sprinkle the cheese over the tortillas, then
sandwich them together in pairs, so you
have 2 tortilla sandwiches. Sit on baking
sheets and bake for 8-10 mins until
golden, crispy and the cheese is melted.
Halve the avocado and spoon out
chunks onto the 2 tortillas; squash into
the tortillas a bit with the back of the
spoon. Scatter over tomatoes, chilli,
coriander and seasoning. Squeeze over
some lime and eat immediately.
