When taking finger food to a group I buy it ready made. Too much trouble to make a lot and many are squeamish about homemade food. I buy frozen small cream puffs; they are always gone first. They are perfectly thawed from home to table. For savory finger foods I buy the small quiches that are okay at room temp. Everyone must like them as both are all eaten. I save the healthy snacks for everyday home eating. Everyone needs indulgence to the bad side now and then. My favorite snack is sliced cucumber with Ranch powder sprinkled on top. Sliced tomatoes with basil and mozzarella balls with olive oil. For sweet I like ice cream.
