I call this my "Ever Ready Salad" because none of the basic ingredients need refrigeration, all can be stowed until needed, and best of all: ya just throw it all together a few hours before you want to eat/serve it. No cooking!
Basic ingredients:
Package of Ramen noodles (any flavor- you won't use the spice packet- save for soup or something)
Can of three bean salad
Can of water pack tuna
Small can of sliced olives
Dump all (don't drain cans) together into gallon ziploc bag, mix well, and stuff in the fridge for a few hours. The ramen noodles are already cooked, so they just need time to reconstitute.
"Recipe" can be varied a lot- chopped cucumber and tomatoes are good additions if you have them.
