Pork and Beans are always something I’ll love eating straight out of the can! Baked beans are great too as well as refried…any beans really! Growing up with just my dad for many years, grilled cheese and Pork and Beans was a staple meal and sometimes you’d be just too tired or wanted something quick and beans straight out of the can cold was always available, tasty, and filling.
I also remember eating and much enjoying canned:
Chef Boyardee (Spaghetti and meatballs were my favorites for the mouthfeel/texture of it cold. Ravioli and Beefaroni were good too)
Beef stew or other more thick ‘hearty’ soups (potato, etc.) and stews I found quite satisfying
Bartlett pears as is in natural juice or drain and cover with shredded cheddar cheese – ‘pear’s & cheese’. It’s so good! (Especially ate this as a kid! The spoonfulls of cheese at the bottom that have absorbed some of the leftover pear liquid was like ambrosia to any kid who was a cheese fiend!)
Chunk pineapple (natural juice)
Whole or stewed tomatoes
Potatoes – mostly a texture thing – just fun to eat!
Corn (plain loose corn, baby corn or creamed)
Spinach, collard, or mixed greens
Vienna sausage, deviled ham, ‘potted’ meats (Ate so much of this, especially the Vienna sausages, as a kid for school lunches)
ANY seafood product (sardines, mackerel, anchovies, salmon, tuna, smoked clams/oysters, etc.)
Any kind of Indian dish that comes in a can or jar (or those silver bags they come in whatever they’re called) like Saag or Palak Paneer, Dal Makhani, Chana Masala, etc. These are always better warm, but they are still delicious straight out of the container.
And then there are those things that aren’t in a can or really eating as in a meal or small snack but more so on a whim or craving like the occasional spoonfuls of jelly/jam/marmalade, cream cheese, whipped cream, peanut or other nut butter (everyone’s done or still does this, right?) etc.
Pork and Beans though is the one that first came to mind and which I still eat and I'll probably always do so.
