SARTracker has good advice.
I agree with browning the roast, and outside, as Bzeitham suggests, makes a lot of sense. Also, agree with the posts about putting the vegetables in at the same time (if on low). I cut them larger than bite size, like cutting potatoes in half instead of dicing. For me, I've found it works better serving that way...everyone gets half of or two halves of a potato and a few carrots when serving. Fresh vegetables are MUCH better than pre-packaged or frozen. I also add celery sometimes, because I like celery (not everyone does). Also, unless you really like the taste of onion soup or similar, I'd just use salt and pepper, maybe a little garlic (or garlic powder) and fresh onion (as opposed to a soup mix). Fresher is almost always better, whether it's the ingredients or the seasonings. Browning the roast adds another dimension, carmelizing the meat if you will. Can't get that on low heat. I used to make a pot roast about 3 - 4 times a month, in various ways. Low heat with a few vegetables is hard to beat.
