Silly food question

I know this is going to sound dumb, but I have a question about 
something Aunt Marge says in PoA.  

"Excellent nosh, Petunia. It's normally just a fry-up for me of an 
evening...."  (PoA 27 US)

What's a fry-up?  As an American I immediately come up with two 
possiblities:  1.  a stir-fry, which seems highly unlikely or 
2. something deep fried, pehaps fish and chips, which seems like a 
lot of trouble

Can anyone tell me what the English consider a "fry-up"?

Cheers!
