In a large dutch oven (I use my La Crueset) put in your beef round steaks, the can of coke, the chili sauce, the onion and the chili powder.
Place into a 300 degree oven for 6-7 hours.
Once finished, shred steaks with a fork.
Give the mixture a stir and serve.
I served the shredded beef on creamy mashed potatoes
Enjoy!
