I am preparing a holiday lunch for 100+ low-income preschoolers, and their parents. I don't have the time, and manpower to prepare roast turkeys. I will have 4 hours to cook, and plate a main, and sides (mashed potatoes, stuffing, green peas, and gravy) and have 3 ovens, and 4 burners to use. I have minimal time for prep the day before and am required to use some form of turkey. Any suggestions? TIA.
