I realize this is a vegetarian dish but I found it when I was looking for a way to use up all the ingredients left in my frig Plus I have some left over chicken – what do you think of adding the chicken?
Hi, Vicki, Thanks so much for your question. I think chicken added to this dish would be just fine! Thanks again and hope you enjoy!
