This recipe was published by Kathy Casey, who, I just discovered, got this recipe from the late caterer, Gretchen Mathers. Although I don't usually like green olives, I LOVED these. The surrounding cheesy-dough goes well with the tart olives. The recipe calls for them to be served hot, but they're good warm (and if you're lucky enough to have any refrigerated leftovers, they make a great late-night snack). I've assembled then frozen them, just baking them for a few extra minutes. They're a bit labor intensive at first, but once you get the hang of them, you can assemble more than 50 in less than an hour. Smaller olives work best. I've doubled the recipe, but even that many will disappear quickly at a party, so I'll triple it next time I take them to a potluck. If you don't like sharp cheddar, medium works well - I've even substituted mild cheddar when I knew I had guests who disliked harsh cheese.
