Do they suck as much as I assume they do?? I don't eat them but could do with something that is convenient to eat for a quick snack if I am for example having a busy day for work.

I am travelling for a training day wednesday, then going back there thursday. Work are too cheap to put up for a hotel though, but thats local government for you.

What is a good thing I could take with me that I can quickly eat when I get a chance. I am going to take chicken sandwiches for the train journeys probably as it could be tricky eating a chicken breast and veg on a train.

Total travelling time is only 2 hours there and 2 hours back so not too bad. Is there a protein bar I can make at home that is actually good? All the pre-made ones are coated in chocolate and I don't understand why except just to try and make them easier to sell I guess.

they are not great, but they are fine ONCE in a while. it depends what kind you buy.
as NROL said, the better it tastes, the worse it is for you.

you can always carry around a ziplock bag of peanuts. you can fill a water bottle with milk and whey. liquid nutrition is probably the fastest way. sunflower seeds in a bag could work.

You could try CLIF Bar, I use them on long bike rides (try the oatmeal raisin walnut) the bar are 70% organic here is a link to web page CLIF BAR | Home

Edit: I'm not sure if they carry these in England or not.

I got this protein bar recipe.

I hope it helps.

Yeah I make my own then I know that Im not adding the crap to it. The only problem with making your own is that they dont last as long.
