Squash is slightly more complex, but is good too, as long as you can prep food /before/ needing to eat it, because the prep is easy enough. Winter squash prep - "cut in half, put brown sugar in it, put in oven at 350 degrees (toaster oven for me), leave for an hour, an hour later be reminded about it when the alarm goes off and be confused because you had entirely forgotten about it and thought nobody else was home and who would be making food, and why is an alarm for food going off, oh wait that's my squash..."
We've been being given lots of free vegetables, so need to take those into account here. As well as the cost of food in general.
Baby carrots and hummus is one thing I've found is really good, except I'm bad at remembering to buy it.
Most brands of microwavable food don't work with my taste sensitivities - and those which I will are the most expensive ones which makes it a lot harder for me, so cheese, bread, foods who's preperation is at most 2 steps and at most 15 minutes (pasta being the hardest thing I can do on a good day and undoable on a bad day. On a bad day most everything is unreasonable, sorting out what food in the house is edible and what isn't takes more than it feels like I'm capable of.)
Leftovers, oatmeal, fruit that you just grab and eat (apples, bananas mostly), tins of nuts
you can actually do a variety of nutritional stuff even with the grab and go stuff - nuts (cashews are my favorite), fruit, hummus, baby carrots, bread, cheese, yogurt, oatmeal... that's my default set currently
if I want to let myself have a nice meal I'll spend the effort of making curry lentils (which is "put red lentils and water up to 1 inch above them in a pot, cook for 15 minutes, put curry powder in when the lentils are falling apart (about 15 minutes later") or so - I have the complete recipe elsewhere, if you want to be particularly nice, when its almost done add in dried cranberries if you like them is a variation we made up.
That's one of my current difficult recipes.
With my life coach we're currently trying to start up is have me eat reliably every day of the week, know what to buy for food, and cook something that is actually cooking one meal a week. (say a simple soup which is what I was supposed to do on Wedensday)
