I found it here. Once I read thru it....I had to make it!
I fixed it this afternoon exactly like her recipe. It was a HUGE hit with my whole family. HUGE.
This evening, dh & I got the evening munchies, & we had just enough left over (I had used just over 3 lbs. of meat) to make a few sandwiches.
I sauted more onions, with some green peppers, & a can of mushrooms (wish I would have had fresh, but canned did ok).
I pan toasted the buns, & then added mozzarella to get all nice and 'melty'.
Here's a picture of mine:
You can't really see the cheese, but it's in there. I savored e.v.e.r.y. bite. WOW.
Thank you Pioneer Woman!
