Tropit, there would be some colourful words coming out of my mouth if that happened to me! I applaud your self-control in simply uttering a sigh...
I like to batch cook, too, and then I make up small one-or two-meal portions to put in the freezer. Larger yogurt containers hold two (or a bit more) good-sized bowls of soup, for example, and small sour cream containers can have an entire ham dinner for one squished in there! (We are not really big eaters in our house, so the portions are quite modest). Reducing plastic waste and food waste in one easy step. :-)
