Tyrrells do good crisps, recently I had their 'Sausage and Mustard' and their 'Sea Salt and Black Pepper' flavour crisps and they were both really nice. Even their 'Honey, Roast Ham and Cranberry' flavour ones were nice.
Beware if your on a diet though (probably wouldn't be eating crisps if you were), as they are almost 30g fat per bag and almost 500 cals +
Kettle used to do a Mango Chilli flavour ages ago, but they don't do it anymore. They were lovely.
I do hate though how Tyrrells, Kettle, Sensations and supermarket own brands produce those big bags. They are too much to resist, as I have just eaten 2/3'rds of their 'Smoked Monterry Chilli and Goats Cheese' crisp bag. Bastards.
