Salsa sauce-any dead easy recipes,or any shop-bought ones you recommend?

[AfriendCalledFive]

I know there are some, like El Paso I think (?), but I can't seem to find any 450g jars of the stuff that I need for a recipe.

Any brand is ok, not fussed. Got rotten cold, so don't want to be mooching about supermarkets for ages. Would rather just go in, get a jar and get out, don't want to spread my germs about.
Thx :)

I quite like the Doritos one it's probably very lowbrow! The green one is pretty mild, red one less so but neither will blow your head off.
