We have a vegetarian coming to Christmas dinner this year. We already have a number of non-meat side dishes, but what is a good, simple veggie main dish. We get a main dish of turkey and ham, so she should get something more substantial too.
I usually will just eat the side dishes and be very satisfied. Or bring my own main dish to eat and share with every one else. As a vegan I have no problem with bringing my own food. Ask the person and see if the side dishes will be enough.
Our Christmas dinner will consist of baked sweet potatoes, broccoli Normandy, mixed green salad and bread. Very satisfying to us.
I am the only vegetarian in my family. I just eat the veggies that are normally prepared for the rest of the family. They are always special from what we normally eat, so they are really a treat. I could make a meal out of mashed potatoes anyways.
