Grilled Chuck Roast with Grilled Potatoes

Another recipe where amounts are hard to write down. Buy enough meat to serve the number of people you are feeding. Generally you can count on 1/2 pound per person. If you use large potatoes, cut them in quarters before parboiling. You can expect men to eat at least 4 potatoes, women 2 or 3. Combine the dressings and the lemon juice and marinate the meat at least 8 hours or overnight, turning occasionally. Grill the meat for 20 minutes on each side. If that is not done enough to your taste, grill another 10 to 20 minutes. Turn the meat and dip in the marinade about every 5 minutes. About 10 or 15 minutes before the meat is done, put the potatoes in the marinade and cover them well with it. Place them on the grill, cooking them until they are golden brown and crusty. You might have to dip them in the marinade a couple of times. Slice the meat in rather thick pieces and serve with a green vegetable and or salad.
