Tender Pot Roast

I've been trying for years to make a good ole falling apart tender pot roast. I have posted requests everywhere. The butcher at the meat market finally told me:
Use an actual Pot or Chuck Roast (I was buying Eye of Round or other more lean roast) He then said to use a Reynolds Baking Bag. I hadn't thought of those in years. Here is what I did and it was falling apart tender!

3 lb. Pot Roast, rub with flour mixed with a little garlic salt and brown lightly in 2 T. margarine

1/2 Onion, chopped
1 Lesuer tiny carrots
1 jar Pepperidge Farm 97% fat free Brown Gravy (or Heinz brown gravy)

After browning very lightly, add Pot Roast to Reynolds Baking Bag. Top with onions, drained carrots and brown gravy. Bake in a 325° oven for 2 hours.

Not only tasted great but there was no pan to clean since everything stayed in the cooking bag.

Enjoy!
