Do you have a bbq pit? Any kind will do, if so
1. Buy the 6 inch tube smoker and a box of pellets, try hickory, mequite or oak from here or wherever you can find it, lots of stores sell them, even Home Depot and Lowes

Fiesta Fajita Seasoning3. partially stuff the tube smoker with foil because you only need to smoke for about 10-15 min depending on the wood you pick and your taste for how much smoke flavor you want so you don't need to fill the whole thing up and waste pellets, fill the remaining gap in the tube smoke with your choice of wood pellet, place in bottom of BBQ pit below the grate and let it burn for a few minutes
4. While it is burning, cut the milanesa across the grain as best you can in chunks of whatever size you chose, and season liberally with the fajita seasoning, then go place on the grate of your BBQ pit above the tube smoker for 10-15 min, play around with this until you get the flavor you like
5. After 10-15 of smoking take it off the BBQ pit and put it in your dehydrator. I use an Excalibur and follow the temperature setting and time for jerky, I can't remember what is it is right now, and let it dehydrate
6. Check it throughout the cycle you set it for after a few hours, I seem to recall maybe about 3 hrs, but I could be wrong.
edit to add note; on the fajita make sure you pick the one that contains salt, because they do sell a salt-free one.
That is it, pretty simple, very good tasting jerky.
