For chicken I like Valley Fresh Premium White Chicken Cuts It mushes up real nice to become shredded. I mix it with a bit of tabasco and put it in soup.
Libby’s Seasoned Beef Crumbles are good in chili.
The Progresso Chili's are good Red, White. I like to ad a pouch of one of the above meats for more meatyness.
I have also pre-cooked ground beef to be added to a can of chili. I like doing that because I can add a onion, and seasoning. I freeze it before it goes into the cooler. It is defrosted by the second day.
