Student Chefs Share Winning Recipes With Sachem Staff

During a display of culinary expertise three teams of Sachem chefs from Seneca Middle School shared their award-winning recipes with cooking managers from each of the Sachem Central School District’s 15 buildings.

The three teams of students who placed at the recent eighth annual Junior Iron Chef competition held at Whole Foods Market in Lake Grove prepared the original dishes they created. Each delicious recipe, which was composed of all USDA-approved, cafeteria-ready ingredients and were served with careful presentation, were then taste tested by cooking managers from across the district.

Teams worked in unison as they navigated the Seneca cafeteria kitchen for the first time while they managed their one-hour cook time with precision. The first-place team, Team Golden Girls, plated their Jardin Burrito filled with eggs, guacamole, Monterey jack cheese, peppers, onions, black beans and corn that was paired with a delicious mango salsa. The third-place team, the Greek Goddesses, presented their Greek omelet, coined Demeter’s Dish, that was filled with potatoes and paired with tzatziki sauce, and the fourth-place team, the Slice and Dicers, served their savory breakfast quesadilla. 

“Today was incredible,” District Chairperson for Family and Consumer Science Mary Louise Faller said. “We were able to give back to our food service staff by preparing a few of our delicious dishes and the students got to show off their culinary techniques.”

The event allowed food service staff to observe each step of the cooking process and gather ideas to bring back to their own buildings to incorporate into the lunch menu.
