Foil Bag Pot Roast

1 3 lbs. Roast
1 small onion, quartered
1 - 1 1/2 c baby carrots
3-4 red potatoes, quartered
1-2 stalks celery, whole

1 tsp. flour
1 pkg onion soup mix
1 cube beef bullion
1 c hot water
salt & pepper to taste

Dust bottom of empty foil bag (or pouch) with flour. Dissolve boullion cube in water and add soup mix upon dissolution. While waiting for this to occur, throw the roast and all the veggies into the bag. Salt and pepper to taste (be careful--those processed soup mixes have a lot of sodium, so don't add too much salt). Pour bullion/soup mix over roast and veggies. Seal it up tight and throw it over a medium grill or medium hot coals for 1.5 hours. Turn it once (if you can do so without leaking) about 1/2 way through.
