I substituted butternut squash for carrots and tinned chopped tomatoes for fresh. I also made my own Italian dressing as not something I normally stock. Thought there could've been a recipe for this as it initially put me off making it.
I'm glad I did make it however, as it tasted delicious! Easy to make and the squash soaked up all the flavours. I used more dressing than specified and definitely wasn't bland as I've seen mentioned in other reviews.
