Heat some oil in a pan. Chop mushroom and tomatoes to the pan and fry. Then add spinach (were using frozen spinach that we've defrosted in the microwave).

When the veg is cooked, take the veg out the pan and put to the side. Place a tortilla in the frying pan and then place your veg with mozzarella and feta mixed in on one side. Fold over the tortilla and press down on the top of the quesadilla till everything has melted together.
