So what do you people usually have, if you have them? Cos of the hours I work I don't often get lunch til 3.30/4.00 pm. So I need something high in energy and low in carbs that I can just grab and munch on the bus to keep me going at work. Any suggestions?

Egg cups are good for grabbing on the go. I found variations on a blog called Kalyn's Kitchen (not sure I'm allowed to link it, but it's easy to find on google). They freeze or just keep in the fridge for several days.

I would also like to know what kind of snacks you all like to have.
If I make bacon or sausage for breakfast, I try to make enough so that I will have it for a snack later. I like to put bacon inside a lettuce leaf with a slice of cheese & a little bit of tomato. Basically, a BLT with no bread.

Not sure if you could take that with you though. I will try to pay attention to what I'm snacking on and come back and post.

Beef jerky

I hadn't thought of Beef Jerky! Good one Loli!

OK, brainstorming for you....

Cheese sticks
Sugar free jello cups
Peanut Butter Protein balls
Atkins shakes/bars - your opinion may vary - I just do shakes
boiled eggs - plain or in deviled with halves stuck together to travel well
Rabbit bag - cut up veggies chunks in baggie
Pork skins - I know, everyone's tired of 'em probly
Bag of nuts, maybe with some sugar free chocolate (keep portion small on choc)
vienna sausages with mustard - I know, but I love them. Yes, I do.
That's all I've got off the top of my head. Hope it helps out.

Pork rinds/celery sticks, cucumber slices used to scoop homemade pimento cheese
