My household is doing Thanksgiving dinner and I need help with a timeline. We've got one oven and we'll be cooking box mashed potatoes, leg of lamb, greens, rolls, sweet potatoes, cornbread stuffing, pumpkin pie and peach cobbler. Our other dishes, like the ham and turkey breast and gravy and cranberry sauce, can simply be reheated. The goal is to get everything on the table by 7 PM. Help!
