4 oz (110 g) Mozzarella sliced
About 24 fresh basil leaves ( dried basil could be used)
2 Tablespoons extra virgin (Italian) olive oil
Salt and freshly milled black pepper
Then slice the tomatoes thinly. All you do now is arrange the slices of mozzarella and tomato in layers, either in rows or concentric circles, on a serving dish.
Scatter the whole basil leaves over them, then, just before serving, sprinkle with plenty of salt and freshly milled black pepper and drizzle the oil all over.
Note of caution; many may eat this with warmed ciabatta bread, but if you are living the LCHF lifestyle, or are diabetic and need to keep an eye on blood glucose numbers, I think a better suggestion would be to eat it with some wonderful thinly sliced ham. Your choice of course.
Another recommendation may be a glass of chilled Italian White Wine.
