Preheat oven to 400. Lightly oil three baking sheets or shallow pans.
Wash and trim stem from eggplant and zucchini. Scrub and peel potato. Slice the eggplant, zucchini and potato, lengthwise, into approximately 1/4 inch thick slices. Rub eggplant slices with a little salt and set aside in a colander in the sink or in a big bowl for about 15 minutes to soften, briefly rinsing with cold water and squeezing out any excess liquid water.
Line 3 baking sheets with parchment paper and place each vegetable on a separate baking sheet. Distribute 1/4 cup oil between the three sheets and sprinkle vegetables with salt (except eggplant if salted already). Toss to coat, making sure each piece is completely coated with oil. Spread vegetables out with minimal overlapping. Roast the zucchini and eggplant for 15 minutes or until tender. Roast the potatoes for about 22 minutes, until edges are lightly browned. Remove from oven and let cool.
While vegetables are cooking prepare the tomato sauce. Add remaining 1/4 cup olive oil and minced garlic to a large heavy bottom sauce pot. Bring to medium heat and let garlic sizzle for about 30 seconds, then add shallots and cook until soft and translucent, 3 to 4 minutes. Add wine and simmer until slightly reduced, another 3 minutes. Add crushed tomatoes, oregano, ground cinnamon and bay leaf. Partially cover and simmer over medium-low heat for 12 to 14 minutes, stirring occasionally. Sauce should reduce slightly. Turn off the heat, remove bay leaf and adjust salt.
