Answer:
technically no
Explanation:
there are 2 definitions of sandwich. one is the food one: 'an item of food consisting of two pieces of bread with meat, cheese, or other filling between them, eaten as a light meal.' the earth isn't food so it can't be a sandwich. the 2nd definition is the verb : 'insert or squeeze (someone or something) between two other people or things, typically in a restricted space or so as to be uncomfortable.' by dropping a piece of bread on the opposite sides of the earth at the same time won't make the earth squished or uncomfortable, so no it can't be a sandwich ( or be sandwiched)
