light salad of yellow tomatoes

Hello to all my friends!
In the summer, when the street is very hot, do not want to eat.
You can prepare here is a light salad of yellow tomatoes. We used to see tomatoes red.
Yellow have a sweet taste and they look beautiful in a plate.
I took two tomatoes oblong shape, a small head of onions, all cut into a plate and added sour cream. Sour cream tastes like yogurt, white in color and slightly salty taste.
Salt can be added to your taste.
Bon appetit!!!
