I had to scroll way too far for this.

fun fact: whole-grain bread is probably healthier than soft white bread anyways due to an increased content in fiber, so there's that ...

Roast chicken on a nice crusty sourdough is amazing. Get some butter or gravy in there it's a hell of a meal

It would if it fell on your head. Checkmate atheists.

Potatoes could. The leaves, sprouts, and underground stems (tubers) of potatoes contain a toxic substance called glycoalkaloid. Glycoalkaloids make a potato look green when it's exposed to light, gets damaged, or ages. Eating potatoes with a high glycoalkaloid content can cause nausea, diarrhea, confusion, headaches, and death.

Also, the sentient mutant vegetables on Atrack of the Killer Tomatoes will definitely want to do harm toward OP.

I'm a vegetarian once removed. A lot of the animals I eat were vegetarians.

He stole the chicken and bread, calm down Mr medieval economy

Depends on time and place, of course. Peasants in the late medieval period in England ate more meat than we do today (about 40% of their calories).

King Richard I was once captured for ransom while traveling undercover trough Austria.

His cover was blown specifically because he tried ordering a roast chicken.

There are a few variations of the details in this story though, a peasant could definitely have owned a chicken and eaten it when it died but it was probably way more valuable to sell it.

Doubtful, most common meal for peasants would have been a sort of stew of vegetables and oats called pottage.

A whole chicken would have been prohibitively expensive either to purchase or in lost money from sale at market, same for pork or beef.

Fish though would be plentiful and cheap and a valuable source of protein. Oysters were considered peasant food until pretty much the 20th century.

Wheat bread similarly would have been a rare luxury, especially made from refined white flour, rye and buckwheat, roughly ground would be far more common.

Yes, they had chickens back then.

Plain bread is a travesty

This isn't plain bread, good sir, this is a baguette! Well, rather small one, but still.

Plain bread is perfectly fine as long as it's not one of those super dry breads

Depends on which era honestly. The medieval period lasted for nearly a thousand years and could vary about as much as one would expect, so for example a very well off peasant during the high medieval period maybe could have eaten a whole ass chicken for a while at least. Probably wouldn't have though, at least not without turning it into soup or a sandwich equivalent.
