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.
