One thing I like to bring to work is "Lasagna in a bowl" and usually add a veggie. Broccoli and spinach seem to work the best, depending on my mood.

It's funny... people say how good it smells and ask what it is. When I tell them what it is :

cottage cheese
small amount of tomato sauce
ground beef (and)
broccoli or spinach

they make all these little "Eww" noises ... but it sure tastes yummy!

I also love pepperoni chips with a bit of slightly melted cream cheese. Yummy.
