Lots of great ideas already here so I'll just give one suggestion of what NOT to try:
Baby Food in jars.
As a single bachelor I thought it was a stroke of genius when I bought half a dozen varieties and took them home to try.
Blecchh!!
OK, here's what I did eat a ton of as I also pretty much couldn't/wouldn't cook.
Pasta with Prego sauce. Lots of it. Almost every night. The sauce keeps well in the fridge and dry pasta on the shelf lasts indefinitely.
For salad it was either raw broccoli dipped in Italian dressing or raw zucchini slices dipped in same.
Easy peasy.
Most other fresh produce would go bad long before I got around to eating it.
Very glad I found a girlfriend (the future Ms. OM) who is a world-class cook.
