Spaghetti? Kind of boring, but easily adaptable for a large crowd. You could sauce w just veggies, then have meatballs for those who eat meat to add. Then you could make some garlic bread and a good desert to go with it.
Lasagna is another thing to make easily for a large crowd.
When I was in youth we always had "boring' stuff like Pizza, Arby's Roast Beef Sandwhiches, Chicken sandwhiches, subs, and hot dogs. |
