If you have tinned tuna, some tortillas and frozen spinach in your freezer you are good to go. To convert it to a full meal serve it with a soup or a salad.
Thaw the spinach and leave to drain in a strainer. Squeeze out most of the water.
Place the spinach in a bowl and add the tuna, jalapeno, salt and pepper and combine well.
Spread half the mixture on 1 tortilla and cover with grated cheese.
Cover with a second tortilla and press lightly.
Heat a frying pan wide enough to fit the tortilla. Then brush the top of this tortilla lightly with some olive oil and place it carefully into the hot pan, oiled side down.
Brush the top of the second tortilla with oil. Cook the first side for about 2-3 minutes and flip over carefully to cook the other side. Both sides should be golden and the cheese melting.
Cut into quarters and serve with sour cream, more jalapenos and a slice of lime.
