Sauces for salads

Hello fellows, Most of the places where we sit to eat, they offer the salads with sauce or also called topic. I love eating salads, doesn't matter what is included inside, but most of all I like when they put only vegetables with oil inside and nothing else. At some places the sauces has so strong taste that I don't feel the taste of the ingredients. That's what I hate the most and I always order salads without sauce. The white one usually has a taste of yogurt or garlic, the red one has a taste of ketchup. I love garlic, also yogurt, but ketchup is not one of my favorite tastes. So I prefer the salads clean of non salad tastes. What about you?
