My quiche recipe (that I modify a little to spice it up) has cheese and tomato...

Line a quiche dish with defrosted short crust pastry sheets.

Mix together 4 lightly beaten eggs, 1 & 1/2- 2 cups of grated cheese, 1 grated zucchini, 1 leek, chopped into small pieces and 1-2 Tb of milk. Pour into quiche dish then layer top with sliced tomato and some cracked black pepper.

Bake at 200 degrees for 45mins.
