Potato soup

This is cheap, easy and really, really good comfort food
1-2 TBS butter
1 Yukon potato, unpeeled and sliced in 1/4” slices
1 small onion diced
1 can broth
Salt and pepper
Melt butter in pan over medium heat. Add onion and sauté 5 minutes until softened.
Add Potato and stir to coat. Add salt and lots of pepper.
Add broth, bring to boil and simmer until potato is cooked and crumbling, about 15 minutes.
Serves 1
My family used to argue about whether the potato should be sliced or diced.
Since this is my blog, I went with sliced.
