This tangy dish was inspired by grandmother, Mamitsa, who immigrated from Greece in the early 1900's. She was a fantastic cook and a real inspiration to the whole family. It's a great hot side dish for a BBQ and easy to make for a small family or a crowd and easy to adjust to whatever is available from the garden or produce aisle. I have created all kinds of variations over the years as more ingredients became more easily available, so feel free to experiment! I cut the potatoes into 8ths, the broccoli into individual florets and the zucchini into 1/2 inch thick coins to make sure the cooking time was about the same for everything. Feel free to substitute any combination of the following cauliflower, broccollini, mushrooms, artichoke hearts, asparagus, roasted red peppers, onions, as much or as little garlic as you like, possibly some cherry tomatoes at the end for color! It's a fantastic way to take advantage of summer's bounty!
