I wish I shopped with a list or a plan, but I don't. I'll usually write down what I really need or am missing, but I buy what looks good and then make meals around what I buy until it's gone. All veggies get washed as soon as I get home.
Sunday: Cross train/meal prep
Whether I'm home or at work, I'll just add hot water and top with a few walnuts. Or, I'll throw it in an empty peanut butter jar and have overnight oats in a jar.
I also chop up celery and put it in a large baby food jar, which works perfectly for one stalk of celery. I steam and portion out veggies into bags. The only thing I don't prep in advance is my lunch salad, which is typically leftover salad from what I picked from my garden for the night before. I'll also throw a sweet potato in the microwave the night before and have half for dinner and half for lunch the next day.
I usually make a big meal on Sunday so we have a few of those leftovers to add to salads or for dinners later in the week. When we ate meat, it was something like crock pot southwestern chicken, but now that we're vegetarians, I make grilled balsamic-marinated vegetables or sweet potato black bean chili from the crock pot.
I have a giant lunch box that was probably designed for a family picnic, which I tote all of this to work with.
And in terms of blogging, tons of stuff can be written in advance and pre-programmed to publish, just like this blog post. I also follow a training plan, which takes the guess work out of working out. I know what the workouts will look like for the next 12 weeks, which helps me plan whether I need to get up early or can press snooze a few times.
