Next, prepare to layer your dish. I like the look of an molded mina, as shown here, but if that makes you nervous, you can layer your mina in a casserole dish, as you would a lasagna.
To prepare a molded mina, I suggest generously oiling your dish, and lining it with strips of parchment to prevent sticking.
Line your prepared dish with the softened matzah, and begin layering.
Add your potatoes first.
Next, add lamb filling, followed by eggplant, with another layer of matzah in the middle.
Continue layering in this way. In the end, fold the first layer of matzah over to seal the edges and brush generously with olive oil.
