It's amazing how many ways there are to cook a roast. When this post has grown to it's limits I am going to save it. It would be fun to start at the top and use each recipe.
My spin on the recipe:
Large crock pot, on low or high depending on the time you have.
Wash the roast, rub in (hard rub) Greek seasoning. Put the roast in the crock pot, lid on and forget about it for about 6 hours. (If you want to add vegtables you may. No water or liquid).
Turn the crock pot off, remove the lid and let the roast sit for about 15 minutes. (This keeps the juice in the meat and lets it cool enough for slicing).
Move the roast to your cutting board, slice in very thin slices. An electric knife is perfect. Put the slices back in the crock pot to soak up the juice created when cooking.
It is very very good.
