Do you just suck it up and wear it home or strap it to your bike somehow? Do you just make sure you have enough storage to put those things and therefore don't have the issue to begin with?
It's hard to tell from your picture but it looks like your bag expands. Does it have a second zipper on the top that goes all the way around the bag? Even if it doesn't expand, it's not that difficult to get 10 lbs of potatoes in a 5 lb sack. Put anything small...socks, underwear, gloves, etc...in the side and rear pockets. Put larger stuff in the top compartment and then roll everything else as tightly as possible in the main compartment. I've been using rack bags exclusively for about 30 years...I hate using panniers...and I live in an area where the temperature can be 20 F in the morning and 75F at night.
If all else fails, I carry a rack strap like
this one to bungee stuff to the top. I don't use it that often, however.
