Delicious mushroom, corn and zucchini quesadillas. This is not an authentic Mexican recipe but a modified, vegetarian version of an authentic easy meal called "sincronizada" which is traditionally made with ham and Mexican Oaxaca cheese. Best served with avocado, green salsa and sour cream. I find cans of Mexican green salsa at specialty foreign food shops, by the brand La Costeña.
You can use canned corn if you prefer.
