CC, many of the stuffings, or dressings, we make are vegetarian, not from conviction but I find the contrast of a vegetable stuffing with the meat to be preferable.
But you want a fast recipe, so might try this.
Use the bag stuffing. I think that is vegetarian.
Saute onions and some celery. Diced green or red (I always love the color contrast) peppers would work here if you wish.
For fluid would use a vegetable broth, homemade, but canned if you can find it.
Or water, not preferable, but you gave a time limit.
Would then add apple pieces, raisins, black and green olives, and maybe some nut pieces.
Would taste and maybe add a bit more thyme or sage (the bagged stuff never is well seasoned in my opinion).
And add a tad of red hot sauce. Find that if you are careful, the little bit of zing is enjoyed by folks who say they do not like food 'hot'. Again, just add a tad.
Just an idea. Have a great time.
