These are absolutely melt in your mouth delicious! You can make them on the grill or in the oven. Even friends of ours that don't care for onions loved these! I would recommend that you use 1 large onion for every 2 people. Some people want one whole onion to themselves so you might want to make some extra! They are also good heated up the next day but we rarely have any extra!
Served in a clear glass dish, this is a beautiful dip made with a cheese mixture alternating in layers with prepared pesto, and topped with walnuts. It's perfect for the holidays! Serve it with toasted French baguette slices.
