Stir in tomatoes, paste, oregano, and seasoning. Allow to simmer 5 mins, stirring occasionally. Add a little vegetable stock or water if a moist sauce is desired. Spread a layer of eggplant on the bottom of the casserole dish. Add a layer of the mince/tomato mixture, then a layer of grated cheese. Alternate these layers until all the ingredients are used. End with a layer of cheese. Bake, uncovered, for 30 mins, until the cheese makes a golden crust. Good source of protein, vitamin A, C, calcium.
