I think whoever came up with putting the french fried version of them on salads and sandwiches was a fucking genius. It's not a steak salad without fries.
Absolutely based vegetable that will get you through a famine. Versatile and delicious, and one of the more nutritious carbs. Just make sure you eat the skin. I prefer them baked or mashed, fry form is still delicious, but feels like you're ruining a perfectly healthy and delicious vegetable.
Also sweet potatoes are great too, but they're actually not related to regular potatoes.
