As a student, i have loads of these...
I had a friend who pretty much lived off sainsburys £10p noodles which to say they were actually pretty good.
Sainsburys/Asda own brand Pasta, 30p a bag, - absolutely fine.
I dont like bread much tbh, but when i did buy it, it was the 40p basics bread to freeze, and for toast, yet again tasted fine.
Yet again i second the Garlic bread, was lovely, specially for about 40p.
You might think this is disgusting, but.... Sainsburys do basics 75p ready meals, and they were lovely! I didnt eat them that often due to having alot of sat fat, but for 75p. What a bargain!
