Slow Cooker Roast with Coke

I've made this several times and I do find that there is no coke flavour left when it is all cooked.  There is a BBQ flavour that is great!

Ingredients

1 (2-3 pound) cheapest beef roast you can find
1 can Coca-Cola
2 cups ketchup
1 package onion soup mix
1 to 2 Teaspoons liquid smoke

Directions

Spray slow cooker with nonstick cooking spray.

Place roast in slow cooker.

Mix remaining ingredients in a bowl and pour over roast in the slow cooker.

Cook on low for 8-9 hours or high for 5 hours.

Good luck taking the roast out of the slow cooker in one piece.  It's going to fall apart.

Comments and suggestions are ALWAYS welcome.
