I added: carrots, celery, walnuts and green beans.

I omitted: lemon juice, garlic, and lemon peel (I didn't have it on hand).

I substituted: vegetable stock for chicken stock.

This was really good, I should have added more butternut squash, it didn't seem to have enough.  The green beans did not go over well with other eaters, but I liked it.  It was said to be too different of a texture, and didn't go with the rest.  The green beans might be better as a side for this dish.

It also needed some more 'oomph'. The garlic and lemon would have added it, I need to make sure I have it next time I make this.

Overall, it was nice and filling, and is vegan too boot.  We're trying to go with more vegetables, and less meat.
