I made this for a funeral dinner a while back and it was a huge hit. Then I lost the recipe I printed out. There are many ‘similar’ recipes like this-but this one is the winner. I’ve spent most of the morning searching, and finally found. Thank goodness. I’ve now saved it in 3 of my boards, haha. Thanks for such a tasty side.
Best veggie side ever! Feeds a small army, and super easy to make.
