Heirloom Tomato Salad

When the temperature approaches the century mark, its hard to find something that sounds appetizing.  
I have a dish that can beat summer's heat, Heirloom tomato salad.
Ingredients:
2          Heirloom tomatos, quartered
1          cold hard boiled egg, also quartered
1/2       shallot, coarsely chopped
1tsp     lemon zest
3          basil leaves, coarsely chopped
            sea salt, to taste
            light creamy balsamic vinaigrette(I prefer Girard's)
