Choose one or several of the foods listed below or think of others to use as the “surprises” in these tasty small pies.
Preheat oven to 375 degrees F. Prepare pastry dough, roll out into 1 large rectangle, and cut to fit greased individual tartlet molds or small muffin tins, approximately 2 inches across. Line each mold with pastry and set on a baking sheet. Beat together eggs, sour cream, and milk; add salt and pepper. Stir in 1/2 cup cheese. Spoon mixture into molds, filling each one 3/4 full. Add 1 slice of seafood or vegetable to each mold, as desired. Sprinkle remaining 1/4 cup cheese over each and bake for 30 minutes. Cool slightly and serve. (These can be baked ahead, cooled, and refrigerated; to reheat, bake at 350 degrees F for 10 to 15 minutes.)
