Tomatoes cut into wedges, some lemon juice, a touch of balsamic, splash of good olive oil (the bright peppery green oil, not the more buttery and smooth yellow oil), salt, pepper, basil, and thyme.
For fancy add in cucumber, red onion, feta, and kalamata olives.
Save the juice from the bottom of the bowl if you make a lot. Chill it and it is a fantastic and refreshing drink.
