Who says a grilled cheese sandwich has to contain bread?! This fun Mediterranean Diet recipe is inspired by a very traditional Greek island dish for squash cooked in layers in a skillet with onions, cheese and tomatoes. I’ve transformed the idea into a sandwich, without tomatoes. You can use zucchini, pumpkin, calabasa, or any other squash you’d like in place of butternut.
Squeeze excess moisture out of the squash by placing it in a kitchen towel and wringing and squeezing for a few minutes.
