bookstorebabe - butter on saltines was one of my favorite snacks as a kid!
a big pot of spaghetti with meat sauce (ugh..for days and days on end. I can't even gag it down anymore)
SOS - but my mom used to make it was a can of tuna instead of meat - so is that still SOS? hmm, I don't know.
Also ate a lot of ramen. ramen with scrambled eggs. ramen with hot sauce.
cinnamon sugar on toasted white bread with margarine.
strawberry jam on generic Ritz crackers.
lentils or beans cooked in the crockpot.
chili over spaghetti noodles
baked potatoes with whatever leftovers were in the fridge dumped on top
and i don't remember if this was a snack when we were broke, or just a weird snack, but my sister and I used to eat jello powder. dry. straight from the box. actually, now that I think about it, probably my mother didn't know we were eating dry jello powder...
