Ok, so the photos aren't that pretty, but just to show that I did indeed try making the fruit and nut energy bars I mentioned the other week, and they turned out great. I based it on the Enlightened Cooking recipe but added some coconut and used brazils and cashews for the nuts. Pretty damn good, although very much on the sweet side - next time I make up a batch I'm thinking of including lemon/lime/orange zest to give it a bit more of an edge, and maybe trying combos with a slightly higher nut:fruit ratio, as the dates and cherries are both super-sweet. 
Best part of these is I added up the costs of all my ingredients and worked out each little square cost me less than 20p. Compares favourably with chocolate bars (even from my subsidised work canteen) and very favourably with Lara bars.
Unfortunately, having one of these in my lunchbox everyday hasn't completely ridded me of my tendency to make impulse cupcake purchases mid-afternoon - still working on this...
