My first choice is always a grocery store...here, even in convenience stores/gas stations you can find pre-packed salads, protein bars, or fresh fruit to get you through in a pinch. If I can get to an actual store, it's even easier...pre-packed or salad bar salads, fruit, etc.

If I am on a road trip, I usually find Subway is prevalent enough that I can get a reasonable-calorie sandwich wherever I am.

Oh I miss El Pollo Loco :( Not one where I moved that I am aware of :(

mandalinn, I agree. On my last road trip I went into a large grocery store and bought all kinds of stuff to snack--baby carrots, prepacked fruit, etc. I love a grocery store. When we were overseas last month the same method worked great. Fruits and veggies are good choices no matter WHERE you are!

THANK YOU all for great advice! I did look on various websites and I really like Wendy's nutritional info. You can build a meal and it calculates the entire thing, and you can add or remove items until you find the right combo. I was on my way there and remembered that I had a WW meal in the freezer at home, so I stayed OP with Southwest Chicken.

The grocery store is a great idea too. There is a Whole Foods about 1 mile from here, so in the future, that may be a good lunch/walk combo.

Please keep adding to this if you have ideas!

I sometimes like to buy organic instant oatmeal that is low cal (I think it's called Optimum Zen by Naturemade, but not sure) and all I need to do is add some hot water. The thing is that I have to be careful with oatmeal because it can be a trigger for me, so I have to feel pretty confident to go for it. I like to take apples with me too. At Costco, I buy boxes of Full Bars in chocolate flavor. They're 160 calories and if I have that with a cup of tea or coffee, it fills me up for a few hours, which is quite nice. Not everyone likes the way they taste, but to me, they are awesome! :) I also love Subway. I get their grille chicken sandwich with dijon mustard and fresh veggies and that's 320 calories and fills me up nicely.

Ding, ding, ding! You have a Whole Foods within walking distance--that sounds FAB!

On our last road trip, we were in the middle of no where WV when I realized that I forgot to pack snacks (I had actually packed a lunch for the road in our ice chestbut no snacks). So we stopped at the local grocery store and they had a reasonably sized organic aisle and we bought various bars and snacks that lasted us throughout the trip.

If you're not the type to eat unless your hungry, make your own survival mix of unsalted nuts and dried, unsweetened fruit. Pre-portion it into little baggies and keep it in your car or desk or whatever. It's a tasty energy boost that can be available whenever you need it. :D

So, I hope i'm not ritterating this, but: chipotle is real good, whole food that tries to use organic/natural when possible. That being said, when you get a salad from chipotle, just have them keep the vinigrette, it's loaded w/cals. if you can afford it, get the guac instead of sour cream, and add lots of salsa for veggie boost. Avoid the barbacoa & carnitas they are fatty, super salty, and the chicken/steak are better. You can "build your own" at chipotlefan.com to get the nutrition info for what you get w/out personally adding up all the individual ingredients. I worked for Chipotle for near 3 years, and my DH manages our local store.

I always get the vegetarian with black beans, sauteed peppers/onions, no cheese, no sour cream and guac on the side. I use their salsa as a dressing instead (I love the hot red one!). I also get plenty of the tomato salsa and sometimes corn.

Whole Foods is a great option for a quick lunch. I usually get an avocado roll with brown rice, then a prepared chicken breast from the cold bar and sometimes a veggie feature from the cold bar. My favorite is the roasted brussel sprouts (Oh.My.God!). I know they're loaded with olive oil, but I don't care.

On the days that I Whole Foods it, I eat 1/2 the breast with lunch and then the second half for an afternoon protein snack.

I vote for a protein bar. I know they are sweetened with artificial sweetener but in a pinch, they are great because they can really fill you up. Salad, OTOH, although healthy etc., will buy me only so much time (unless it's topped with chicken breast or something).
Somebody mentioned protein bars with 10-12 g of protein. I aim much higher and I always buy bars that have around 25 grams of protein or so. You have to watch the calories (if you are a calorie-counter) though. But, I also bought a box of some protein bars in Walmart that provided around 30-31 grams of protein each (each was over 300 calories) and often, only half of the bar is enough to get me out of the worst hunger.
Granted, I don't spend too much time on the road so it may be different for you but I think protein bars are really good staples to have around.

I was going to suggest this too and if they also have a deli then you can buy healthy meats to top that salad.
