Your guests won't even know what they're eating, and did you know that snails are a very healthy meat?? If you are really, really squeamish, use canned smoked oysters or mussels. But this is a nice quick starter, or an extra to serve with meagre leftovers (which is what I used it for!) Escargots or snails come in cans, usually in two sizes. You need to look at the label to see approx. how many snails are in the can. The seasonings are fairly accurate, but really, this can be used to taste. Instead of black pepper, hot sauce can be used. Our phyllo comes in large sheets and I did not go as far as measuring it. This is an ideal starter to a dinner, served with arugula as a garnish.
I have recently made this with 3-layer rounds of phyllo, pressed into muffin tins, and I put rounds of phyllo on top. I used it as a main dish with a salad and thingies, and instead of feta I used low-fat camembert plus walnuts in the filling. Yum!!
