Flour tortilla taco salad "bowls"
I finally bought two "shapers" to bake tortilla shells in the oven with - I was having horrible luck finding just the right thing to shape them on so the $15 was worth it to me - I spray them with PAM and bake for about 10 minutes. A little more chewy and less crisp than fried, but less guilt ;) and still darn good. These are the ones I bought:
You can also find a similar cage-like contraption for the fryer - just search for "taco salad bowl fryer" and a lot of options come up.
In either case you can use a pre-made 8-plus-inch tortilla
'I just use a custard dish or somesort of other right size dish and spray it with cooking spray. Take a pre-made flour tortilla, brush lightly with oil (both sides) lay over dish and bake in a 375-400 degree oven for about 8-10 min. It takes a few times to get the right size dish and right length of time in oven, but it's pretty easy to do. I'm sure you can fry them too, but this method has a lot less calories. Hope this helps.
