Something else you might find helpful is to make things like salads a bit in advance.
I’m a SAHM, so I have a somewhat different schedule than you do. However, I’m trying really hard to lose weight. I eat lunch when DD goes down for her nap. By the time she does, I am really hungry, and I am unlikely to take the time to make a salad. However, if I make up a salad first thing in the morning and put it in a large Tupperware-style container, all I have to do is pull it out, put a little dressing on it, put the lid back on, shake it vigorously (this is a great trick to make sure dressing is evenly spread through the salad but to not use very much of it!), and then eat it.
For me, a standard salad is:
–A lot of greens–spinach, romaine, etc
–A chopped bell pepper
–Two sticks of string cheese, cut up, or two slices of swiss cheese, ditto
–1/3 cup frozen corn
–Some chopped red onion
I’ll layer this all in the container and put it in the fridge, then pull it out, add dressing, salt and pepper, and eat it for lunch. Very easy and healthy.
Insofar as dressings, by the way, a lot are really caloric. I’ll make my own. My favorite is a tablespoon of raspberry balsamic vinegar and a half tablespoon of olive oil. I just pour each over the salad; the shaking mixes it up. It’s gooooood!
