I work close enough to home to lunch with DH on leftovers, salads or something he conjures up.
And keep a quart of this in the work fridge when I can’t or want a snack that isn’t a bagel or pizza.
Its high in sodium so not a daily indulgence but its pretty good.
My WFH lunches are often last night’s leftovers. I also keep some quick frozen foods and bagged salads. Lunch isnt a big meal for me. When I was in office, it was usually salad kits or leftovers, with tuna salad or ramen in a file drawer as a safety net.
I’ve always been a meh on packed lunches, but I do try to bring lunch at least half the time because it’s financially responsible (booo - no fun). I am fairly anti-leftover though, but will do so when I have food to get through (extra pasta, extra rice and proteins) and it’s food that heats up well without causing too much offense in the kitchen. That is already limiting based on what I eat, since seafood is on the menu often. I bring in “instant” lunches (noodles, a frozen meal, can of soup) to supplement. Will have to grab a photo the next time I bring something more interesting.
