Have you thought about a potroast instead of oven roast? I make mine in a dutch oven ...brown it first and then pour a coke over it. Also a packet of dry onion soup. Cover the roaster and simmer for about 4 hours and this makes the most tender, moist and yummy potroast.

hmmm....your dinner sounds yummy!

I made a 30 Minute Meal last night and will go find the recipe
