I have eaten too many poor versions of this in restaurants etc. Perhaps my tastes are not developed enough but I need stronger flavors than a rubbery slice a cheese with a slice of tomato and a drop of balsamic.
4 medium tomatoes sliced 1/4" slices
8 oz Fresh Mozerella sliced
1/4 cup ev olive oil
3 Tbs balsamic vinegar
2 Tbs fresh basil chopped
3 cloves garlic chopped 1/2 tsp salt
crushed rep pepper to taste
Black Pepper to taste
Alternate and overlap tomato and cheese slices
Mix remaining ingredients pour over tomato cover and rest for at least 3 hours
