1 to 2 cans Diced tomatoes (better if they have green chilis in with them
Seasonings like: garlic powder, season salt, salt, pepper, and any other meat seasonings you like.
1 to 2 can of green chilis (depending on how hot you like it)
Place all ingredients in a crock pot. Add probably 1 cup water. Let cook on high for like 5 hours and then check. If cooked, then take the roast out and shred the meat. Add the shredded meat back to the pot and simmer for 1 hour. Serve on tortilla shells. Serve with rice if you like. Also can top with cheese or sour cream. The roast can be cooked over night if you think it will be a tough one. Just to the roast and plenty of water and some seasonings. Cook on Low over night. In the morning if cooked take the roast out and shred it and then add the tomatoes and green chilies to the crock pot and meat. (Make sure to pick out any access fat in the crock pot before add the tomatoes and green chilies.) Simmer on low until ready to eat.
