I am seriously having to fight the urge to start quoting the spam sketch here... spam spam spam.... no must resist!!!
Seriously as a kid in the 70s-80s, I think pasta salad with spam chunks was a staple of every household in the midwest (and likely elsewhere) in the summer. I can not say I am overly fond of spam as a food like substance, but I do not mind SOME in reasonable quantities in a dish that balances the flavor I HAVE been known to take a can and make up a pasta salad 2 days into the woods on canoe camping trips since no refrigeration of ingredients is required.
(I can't say I actually have a "recipe" for it. I take ingredients along since they are mostly staples of my camp pantry and put them together til "they are about right" for this one)
Camp Pasta Salad
<Note: make substitutions according to your taste>
Boil Pasta in (kosher or sea (<edit>if you prefer iodized salt, that is o.k. too as long as you salt the water til it is as salty as a tear or sea water. just the foodie in me coming out saying stick with the fancy stuff:) )) salt water (I am partial to using macaroni as it packs compact but I prefer riggatoni or bow ties for my pasta salads) until pasta is al-dente or cooked to preference
Strain pasta (preferably over a grass/leaf/moss grease pit and burn the starch covered grasses) and add your choice of the following or your own preferred options
1 can mushrooms
1 small can black olives
1 shredded or better yet match stick juliened fresh carrot
slice and add some grape tomato wedges or halves
cube and add some spam (for a couple people a half can is probably plenty, for a full family, 1 can should be more than enough)
add italian seasoning, or a mix of fresh savory herbs
cube a small block (8oz) of cheese (I prefer a mild cheese in this such as colby (yes when air tight cheese can store without refrigeration. the harder the cheese type the better it will hold)
optionally some capers are a good touch
(you can add other ingredients such as sliced or diced peppers, but I personally can not eat them, so I tend to leave them out of my recipes) according to your own taste. I used to have a friend who liked chick peas in her pasta salad, so that is also among the many options you may try.)
toss with olive oil til coated, but not dripping.
serve with artisan bread or crackers and drink of choice.
