I try to take left overs from dinner, or if I'm in a hurry I grab one of the new Atkin's Frozen meals out of the freezer. I've also taken a salad with chicken, cheese and bacon bits.

I also do the leftovers route, most of the time. I always try to make extra protein for later meals, and mix up different veggies or top a salad. My diary is open if you'd like to look. Just omit any potatoes or fruit you see for lower carbs.

I have to agree with everyone else, I usually plan my dinner so I have leftovers for lunch the next day. If I don't have leftovers than lunch is uaually 4 oz of cottage cheese and some veggies.

I keep hard-boiled eggs in the company fridge for snacking whenever I get the munchies. For lunches, I can bring one of those individual tuna pouches, combine it with one of those eggs and some mayo and/or mustard, and have a little tuna salad.
Other ideas...
Mozarella stick and a thin pickle spear wrapped in a slice of lunchmeat.
Or, the other way 'round, use some leftover fajita-sliced chicken or chicken fingers and wrap it in a slice of cheese.
Can also bring a hollowed-out bell pepper and put cheese / meat inside, and eat it either hot or cold.
And, as everyone else said, last night's leftovers are always a good choice.

Good luck to you!

Low carb tortilla addict here too. Nearly every day I have one with some lunch meat and cheese. And either low carb yogurt or a cheese stick. Later in the afternoon I might eat some turkey pepperoni or carrots dipped in hummus.

Every Sunday I make 1 doz. hard boiled eggs. On Monday I bring in 10 eggs and a 10 ct. pkg. of Babybel light cheeses. For lunch, I eat two eggs, two cheeses and half a bag of steamed veggies (steamed the night before at dinner). Sprinkle on some spices and YUM!

Bonus: instant portion control...my downfall!

i make a Salmon or Tuna salad and Low Carb Flaxseed bread.

instant sammich!!!!

Back the bus up! There's low carb Atkins frozen meals?! And low carb yogurt? I feel like I've been living in a deprived cave... *runs to scour the Internet for the above mentioned items*

I've never heard of low carb yogurt, but I use plain, whole milk yogurt, which has 6g carbs, 5g fat, and 4g of protein in half a serving (which is actually a lot, with regard to yogurt). It's not super low carb, but it's not bad either and it's got a pretty good profile with the fat and protein in there as well. Plain, full fat Greek yogurt has an even better profile (5/5/9 c/f/p), but it's very difficult to find the full fat Greek stuff around here.
