Allan Law is on a mission to feed hungry people in his city, one sandwich at a time. The retired schoolteacher has spent the last 14 years making and delivering sandwiches, along with other essential supplies, to the homeless and hungry on the streets of Minneapolis. Law works the night shift, leaving his home (a tiny apartment filled with refrigerators) around 8 p.m., returning at noon the following day.

“He is a rolling, problem-solving care center on wheels” says Steven Aase, who works with Law at his non-profit Minneapolis Recreation Development Inc.

Law estimates that he gave out 520,000 sandwiches last year.
