Maybe not that much smaller? The density of meat is close to 1gm/cm³, that of the sun about 1.41gm/cm³, but the sun is relatively small for a star and larger stars are less dense.

I’m neither an astrophysicist nor a food expert, but sausages have lots of carbon and contain a reasonable amount of water and thus, oxygen, so I don’t see young stars match them chemically. Maybe, some really old ones will, fairly short befor they run out of stuff to fuse.

If you limit things to a star’s atmosphere, you may have better luck (https://en.wikipedia.org/wiki/Carbon_star)

With the pressure coming from the inside of the star from burning fuel, I think this meat-star would implode since it is just meat. Unless of course sausages under pressure emit energy. How much sausage would it take to start a thermonuclear process?

What exactly happens would probably depend on what type of star it would turn into, give the elemental makeup of meat.

I'm assuming that pressure would cause temperatures in the middle to rise high enough to break everything down to its constituent elements, and then some sort of fusion would start, eventually breaking down the entire thing.

I bet it would be a _very_ messy process, as things explode and implode, burn and outgas. Eventually things would probably settle into a fairly unremarkable star, except with very odd proportions of various elements.

Depends. If it is proper spicy - think Balkans, Mexico or Thailand... probably less than you think.

So what your saying is that it would cook itself as it collapses and somewhere in the process there'd be a point where the sausage is perfectly toasted?

Well, the water in it would first heat and turn to steam as the Chorizo collapses in on itself, which would eventually result in a steam explosion and a Chorizo Mass Ejection. That might disrupt the cooking process a bit, but you may also get some perfectly-cooked Chorizo launched your way.

I don't think a steam explosion would be enough for a mass meat ejection. Stars regularly undergo fusion and that isn't enough for mass ejection unless it it becomes a runaway process in the case of Stellar death

The steam explosion is based off two assumptions: You're starting with cold sausage that heats up as it coalesces into the star, and that the steam gets trapped by the solid mass of sausage above it. Stars normally coalesce out of hydrogen that doesn't need to go through as drastic of a change as a sausage would when transforming into fusing plasma. My assumptions are probably at least partially incorrect because my field of expertise is really ribs and brisket.

Randall Munroe covered this in his Mole of Moles thought experiment.

"What would happen if you were to gather a mole (unit of measurement) of moles (the small furry critter) in one place?"

Sausage != Meat.

(Might be for chorizo but I'm from the UK)

You silly sausage...
