A lot of members here who work like you will cook up stuff on the weekends that will give them good, clean, grab-and-go food during the week. Crock pots are used a lot. Or you can roast up 3 times as much chicken as you need and then you've got chicken to go for a few days. You don't have to live on green salads only though those are good for you if you use the darker leaves like romaine. Head lettuce is pretty useless nutrition-wise.
Cooking up dark leafy greens (chard, spinach, kale etc.) is really very quick and tasty. Of course, if you aren't used to them you might have to ease into them slowly. Once you cook them up right you might get hooked!
I like to make simple but delicious meat salads that I can wrap with lettuce (I avoid breads). Or you could make quick sandwiches with them if you can do grains. My 3 favorite salads that I keep in the fridge are tuna, chicken and egg. Adding some fresh, chopped herbs to these can really make them spark. Tuna/thyme, chicken/basil/thyme or sage, egg/basil and/or dill. those are just ideas but you can mix and match to your own liking.
Any time you cook something just make twice or even three times as much as you need then it is there for you and even for other family members to help themselves.
There are many, many snacks that are easy too. I like to have "dips" for veggies and fruits handy. My favorites (these days LOL) are hummus (homemade not that yucky pre-packaged stuff) and cream cheese/onion/dill mixture to dip apples or jicama or carrot sticks or to fill celery sticks with.
A couple of terrific packaged snacks to keep in your purse are Tanka Bars (meat) and Lara Bars (fruits & nuts). Having those handy can help to resist junk when you are away from home.
What are the foods you like? Maybe we can supply you with a recipe or two that is quick, yummy and easy to fix.
Also, if you aren't already a member of the Clean Eating & Recipes team I encourage you to join. There are lots and lots of recipes there.

Hospitals are terrific for traumatic care; for acute care. They do a really, really good job in saving lives when it’s a sudden bleeding emergency. But in terms of chronic care, they’re terrible; in terms of the illnesses that most people have, endure, that cost the most money, that last the longest and ultimately die from. -Dr. Andrew Saul
