Layered salad is great for big crowds because it doesn’t require a separate bowl for each salad fixing- instead it’s all together. So definitely look a recipe up for that, pioneer women has one that I will post later. As for the main course, italian food is easy to make in bulk. You could do lasagna with fall vegetables or go old school with cheese and meat! Another easy thing to eat are sliders, you could get creative and impress everyone with different kinds of mini burgers.
