Heat up a heavy bottomed pan or pot and add 2-3 tablespoons oil. Once the oil is hot, add the cut eggplant into the pot. Fry until golden brown.
Take out eggplant and put into a bowl or plate with a paper towel to soak up the extra oil. Let cool.
In the meantime, cut the tomatoes into squares and mince the garlic clove. Combine in a small/medium bowl.
Add the fried eggplant to the tomatoes once cool.
Add the mayo, sour cream, salt and pepper to the bowl and mix well together. Serve.
Notes
Meat-lovers alternative: Cut up a chicken breast into small pieces/squares and fry in oil. Add to the salad. You might need to increase the amount of mayonnaise and sour cream as well as salt and pepper.
