I been doing this fer many a year. Buy some hotdogs (I get the 79 cent ones) Slice down about 1/3rd a one side, roll it over an cut that in half. I find a good sharp chef knife works best. Put them strips in yer dehydrator and dry em up nice. Now it aint that high dollar stuff, but they be mighty tastey and perty darn cheap! Play round with different brands an kinds ta find what suits yall best.
