Hi. I am having about 12 people for Thanksgiving, of them 4-5 are
vegetarian. So I am making Turkey but all the rest I am going to make
vegetarian. Some questions:

1. A stuffing/dressing receipe (Wild Rice with Goat Cheese Stuffing)
calls for 1.5cups chicken stock and 1/2 cup coarsely diced chorizo. I
was going to leave out the chorizo and replace the chicken with
vegetable stock. Will this taste OK?

2. I want to have a vegetarian lasagna for a main dish for the
veggies, but am feeling overwhelmed with the work on Thursday, can I
make it ahead keeping it in the refrigerator - perhaps, assemble but
not bake - and then bake it on Thursday?

3. I have seen info about preparing the potatoes for mashed potatoes
ahead of time, keeping them in water with a little white vinegar. Can
I do this overnight or will the vinegar start affecting the taste?

HAPPY THANKSGIVING and MANY THANKS for your help!!
