one of the things that our girls have an allergy to is eggplant, so i have to wait until they're not home. we didnt have any lamb mince and i couldnt be bothered making a white sauce, so i did this instead in a baking dish.
bottom layer - 1 onion, sliced and sauted
2nd layer - eggplant sliced thinly and sauted
3rd layer - potato sliced and microwaved
4th layer - pour bottle of pasta sauce on top
5th layer - grated cheddar cheese and breadcrumbs
6th layer - proscuitto (or bacon or spinach or whatever)
7th layer - eggplant sliced thinly and sauted
8th layer - potato sliced and microwaved
8th layer - grated gruyere cheese (or parmesan), a drizzle of cream and breadcrumbs
Bake in a moderate oven for 25-30 mins. I covered it for the first 15 mins and then uncovered for the next 15. Yummy.
