Crock Pot Pot Roast (with beer)

So, this is so simple I hesitate to call it a "recipe" but I promise you won't be disappointed!

1 Sirloin Roast (This cut is the key for ANY pot roast, trust me!)
Garlic Cloves
Onion
Potatoes
Montreal Seasoning (or any other garlic/pepper/salt seasonings you have)
1 Crock Pot

Place roast in crock pot. Stab meat with paring knife and make pockets into which you will place peeled garlic cloves at random. Sprinkle with Montreal seasoning. Place whole, small red skinned potatoes on top.(Don't bother to cut them up, you can do that later) Add chopped onion (about 1/2) just on top of the meat. If so desired, you may also add more root veggies like carrots to the mix. Final touch: one can of beer. You pick the flavor. Place crock pot on low and cook it "low and slow" (the other key to a good pot roast) for 7+ hours. Come home to the smell of yummy goodness- separate components to serve...with something green- I insist!!! (can o green beans is good and quick or roasted Asparagus pairs nicely) and make fab gravy to accompany (recipe to follow).
