I think the term that you’re looking for is **“finger food”…**which refers to snacks one can eat with their fingers (sandwiches, chips, deviled eggs, samosay, etc).
Generally speaking, the word** “sandwich”** is used for a meal-sized sandwich…whereas the term **“finger sandwich” **refers to mini or finger-sized sandwiches served as as a snack/appetizer. They’re also called tea/petite/mini sandwiches. In the British culture especially…finger sandwiches are often served with tea.
I used the term, “finger-sandwiches” in my previous post to make a distinction between the **size **of the food…not the manner in which it is consumed.
