You would have to substitute the salsa for chopped chipotle peppers in adobo which comes in cans. I think you can get it at sainsbury's or waitrose or for sure any mexican specialty place. The cilantro for garnish is the same thing as 'coriander' if that helps.
Shredded chicken in tomato chipotle sauce is also called 'tinga de pollo'. I vouch for it being good. This is probably a more trustworthy recipe source: http://www.fronterafiesta.com/cook/tacos-enchiladas-tamales-tostadas/30-chipotle-chicken-tinga-tacos Of course you can just make the tinga and eat it in a non-taco environment.
