32. Potato Salad
Calories per serving: 358+, varies by recipe and ingredients
Potato salad, despite the word "salad" in it, has very little in common with other salads.
It's one of the highest in calorie salads one can find.
With all the mayo and the potatoes you are in for a very nutritious meal, add a few slices of bread and a fresh squeezed juice and you've got around 800 calories right there.
A very nice way to put on some weight!
