I just made a small batch of this. I didn't measure the meat, but I think it was a little under a pound. I used 1 cup of TVP and about 1 1/3 C water.
I melted down about 2/3 C frozen onions, added salt, pepper and garlic salt,
the meat, water and TVP. I cooked this until the TVP got soft. The TVP adds a lot of volume to the meat. I might have used too much. Regardless, it is delicious. The TVP has a similar texture to bulgur, which I like.
I would have used bell pepper and fresh herbs and garlic, but my DH won't eat any of this and I want him to try it. The mix was tasty enough just "as is" that I kept sampling it. LOL.
