I freeze just about anything and everything! Most things freeze well, even though they might not have that crispy edge anymore -- but in general the flavor is still fine. I like the idea of roasting some vegetables and keeping them on hand, either in the fridge or the freezer. Even just having some leftover chopped veggies in the freezer can speed things along. (I am actually eating a bowl of roasted veggies (with miso, rice vinegar, and smoked paprika on them) as I type this.)
Another nice thing to have on hand is a cooked sweet potato or two. You can just slice one open, scoop out the guts, mash them, mix in whatever you want (I recently tried a recipe that had you add pineapple, coconut milk, cinnamon, and walnuts -- yum!), then place it all back in the skin and eat. Super fast if the potato is already cooked.
Banana "nice cream" is a guilt-free sweet treat, maybe for a snack at work if you have a freezer.
Yes, Oh She Glows is fantastic. Veganricha.com is also excellent, especially for her Indian food. I also pull some vegan things from mynewroots.org (also mentioned above) and halfbakedharvest.com (not a whole lot of vegan food, but the things that are vegan or can be veganized are very good -- try her spicy southwest quinoa bowl!). I also love straightupfood.com and thevegan8.com. Real food, not terribly complicated. I think people (not you, necessarily, but people in general) have this idea that vegan food has to be complicated. It really doesn't!
I'm not a huge salad eater (I realize how odd this sounds, as most people think vegans live on lettuce), but I've seen some very nice make-ahead salads that are layered into a jar with the dressing on the bottom. I do make a kale salad with Chef AJ's Hail to the Kale dressing (easily found via Google, though I don't see a link to Chef AJ's official website). That will last for a couple of days in the fridge without wilting.
I travel for work, for about 6 days at a time, so I take my frozen meals with me. You can take them in your carryon as long as they're completely frozen. Or you can take them to work and let them defrost by lunchtime, then warm in the microwave.
Overnight oats are also an easy breakfast option, for home or work or travel. And obviously smoothies are easy to make at home and take with you for a mid-morning snack at work.
