I mean, whenever I hear picky eating, especially pickiness about a savory food, I imagine a person who lives on hostess, mountain dew (any kind), fried foods, and formed meat pastes (Hamburgers, hot dogs, chicken nuggies).
In general, the food that I was raised on, before I learned how to cook and eat a variety of foods.
I absolutely die for Kalamata olives lightly dressed in olive oil and Italian spices.
