My current obsession is quesadillas, very cheap and super easy. The mix can be whatever you want, I use shredded chicken, grated cheese, fresh coriander, red onion and a bit of chilli, but really you can throw in whatever you feel like at the time. You stick a couple of handfuls on a tortilla, top it with another tortilla and squish it down a bit, then into a frypan. When one side is toasty, flip it. Then when its nice and crispy, take it out, cut it into wedges, and serve it with sour cream and guacamole and salso, the usual stuff for dipping.
