I am also a vegetarian, so none of these.
I also was raised Catholic and never heard of no meat then. In fact, my very religious grandmother always makes more than 1 kind of meat.
I haven't decided what we'll do yet. My ex, son & I will probably have turkey loaf (for them..lol) and homemade mac n cheese. My mom & step-dad are coming the 2 days after Christmas and I have no clue whatsoever what to make then. Then we'll celebrate with my dad on New Years at their place, so it'll probably just be fun vegetarian-Mari friendly.
