A grilled chicken sandwich with tomatoes and green beans at Chacarero in Boston.

Otherwise-harried people will regularly wait on Chacarero’s long lunchtime lines without complaint. It specializes in Chilean sandwiches on round rolls, somewhere between hard and soft, filled with steak, chicken, or both; tomatoes and green beans; Muenster cheese and avocado spread; and hot sauce. It’s hard to say what makes the sandwiches so compelling. The green beans go a long way, though.
