Way to go to our T99 students Mary, Zhixin, Kendrell and Samantha who competed in the First Annual Transition Culinary Competition hosted at TCD! 👩‍🍳🍽️

Teams had just one hour to create a breakfast dish, and the T99 team chose a bacon and veggie quiche and a peaches and cream upside-down pancake! The judges were wowed by the taste, presentation and teamwork.

We earned second place and rave reviews from the judges!
