1) Buy some gummy green army men at the local store (here in Canada we found them in the candy section of a store called Bulk Barn).
2) Fight a battle using whatever rules set you like - we used our house rules, Two Minute Wargames, because we were hungry.
3) Eat the gummy army men.
Advantages:
1) no painting or basing required
2) easy storage (a plastic bag before, your tummy afterwards
3) green gummy army men are appropriate for most periods from 1940 on
Disadvantages:
1) Limited variety and flavours of green gummy army men available
2) Opponent is tempted to eat your troops while your not looking
3) Scale and accuracy of the minis is a bit dodgy
Enjoy this brilliant idea, thanks to my son John and I!
