Oh, yes indeedy! I will occasionally buy a can of sardines and eat then with soda crackers. It reminds me of enjoying them with my grandpa.
Does anyone remember the "blind robins", which were little whole salted/smoked fish sealed in a plastic packet? You ate them head, tail and all. My grandpa liked them even more than sardines and, surprisingly enough for a child to like them, so did I.
And talking about nasty but good snacks: Vienna sausages and Underwood potted ham. Haven't had them for probably 40 years or so. Do they still make them?
