High-school students of the Sidwell Friends School have long padded their résumés by indulging in an extracurricular feeding frenzy. But competition for Ivy League acceptance trickles down, and even Sidwell fifth-graders like Eleanor Terry are no longer immune. In addition to the soup-kitchen work, theater perform ances, poetry workshops, and competitive athletic events that Eleanor undoubtedly enjoys, she exhibited her culinary prowess (and vita savvy) by creating an award-winning sandwich called the “Basic Jumble.” The sandwich, a tempting mélange of cream cheese, cucumber, smoked salmon, and puréed acorn squash spread on zucchini bread, won Eleanor a third-place prize of $100, plus $100 for Sidwell, in the Ziploc National Sandwich Day contest. Could such a Booeymongeresque creation be the work of hands as small as Eleanor’s? If not, Sidwell progenitors aren’t the only ones in this Terri-Shields-act-alike contest. The winning sandwich, “Chicken Surprise,” created by Chelsea (Coincidence? We think not!) Roush of Southern Nazarene University School for Children in Bethany, Okla., requires that its maker be able to slice an onion, cook a chicken breast, and have the palate for a sandwich that combines both with cream cheese, bananas, and grapes on sourdough bread. Chelsea is in the first grade.
