With a casserole dish. Layer ' zucchini , onions , meat, rice
Top with cheese, crumb mixture, and spices
Mix tomatoe paste , water,sugar in a bowl. Pour liquids all atop entire casserole.
Bake at 325, 90minutes. Mmm
I dice the onions. And coarse ly grate or chop zucchini. Use Parmesan in mine and mozzarella ( sometimes fresh rather than grated stuff) I look at this alot as a Parmesan dish- a la chicken Parma , eggplant Parma .....
