OMG! This is without a doubt the very best pot roast I have had in ages. Part of the reason my be that I used a rump roast and I cooked this in my crockpot all day. It was the most tender roast I think I have ever made. I love the flavor of this roast with the onions and Catalina dressing. I used one and 1/2 bottle since I had a partial bottle from another recipe. Cooked the roast about 3 hours with just the dressing and onions, then added in the potatoes and olives and threw in carrots too the last 4 hours. I always want carrots with roast. So, great will make again. Wish I could give this more than 5 stars.
