I used to do Flex, but now I do Core which gives me a bit more options, like more whole grains and beans for protein.
I eat in at work most days. To tell you the truth I generally take last nights dinner leftovers. I make enough for DH and myself to each have a decent lunch.
Now on Core, I'll cook up some couscous, add 1/2 cup of beans or canned veggies. Add some tuna mixed w/ff mayo and additives and then I'll have 1/2 cup ff cottage cheese.
Not to get on a Core rampage, but you can eat more things, not worry about points, (you still get 35 freebies a week). The point of this option is to eat until you are satisfied, not full.
When I was on Flex it was either leftovers, sandwiches or soup with a salad or some green beans.
