There may or may not be an actual trick for making a flour tortilla puff up and get just the right amount of crispy, but my toaster oven sure knew what to do this morning. I was just trying to heat up the tortilla, but when the toaster dinged, I found a perfectly puffy round tortilla. Probably a fire hazard now that I think about it, so if you do try this at home, use proper caution. I punched out a hole in the top and filled with warmed salsa and avocado. Served with a side of chipotle mayo of course. This would have been just as tasty with a flat tortilla, but it wouldn't have looked as cool.
I got a whole bunch of avocados from so-cal avocados , so expect them to be a more regular feature. Mostly I just eat them with a little soy sauce or salt and lemon or balsamic vinegar.
