Yes, I concur... totally awesome! I did my first ABTs last weekend, and everyone that had some thought they were great too. I'm making a couple dozen for the super bowl.
I know there are tons of recipies, but here is how simple mine was (not taking claim for it)...
Cream Cheese (softened a few seconds in the microwave)
Shredded Sharp Cheddar (mixed into softened cream cheese)
I don't really think the amounts are too critical, just so long as you end up with a useable filling. I stuffed jalapeno halves with the cheese mix and wrapped each with a strip of thick cut bacon. Smoked for 1 - 1.5 hours... DE-licious.
