If you do decide to venture out of the airport for breakfast, you may be able just catch a bus to Nashua from South Station. Not sure how many companies run from there, but there may be more options from there, as well. Also, just as an FYI... Taking the silver line from the airport to South Station is free. (It will cost you (around $3) if you go back to the airport.)
