The concept is simple - 2 fried corn tortillas with melted cheese and salsa between them.
Fry half a red onion in a pan with a little sunflower oil, then add spices. I'm lazy and buy packets of fajita spice mix (Discovery in the UK is vegan), from which I use about a quarter.
When most of the liquid has boiled off and it tastes good, transfer to bowl and wipe out the pan.
In a second pan fry a corn tortilla in a little oil. When the edges start to brown flip it over and cook the other side.
Whilst this is in progress fry the other corn tortilla in the original pan (again with a little oil) and place meltable vegan cheese on top.
When cooked both tortillas should be golden brown and starting to go crispy, without burning. Carefully remove the quesadilla from the pan (using 2 spatulas slid underneath) and transfer to a chopping board. Divide into quarters with a sharp knife and eat immediately.
hmmmm, I really want one of these now!
