1. Prepare white or yellow sweet onion by slicing in thick slices,
place in plastic bag or glass jar with ice water, seal and refrigerate
until ready to use. This makes the onions very crisp and juicy. 2.
Slice a vine-ripened tomato into thick slices. Mix sour cream, chopped
green onions, bread crumbs, Worcestershire sauce and lemon pepper
seasoning. Mix this in with the ground meat until combined well. Shape
into 4 patties. 3. Cooking the hamburger patties: GRILL: Place meat
on grill over hot coals and cook to desired doneness, turning only
once or twice. 4. Grill: Place meat in grill pan; grill to desired
doneness. 5. Mix the mayonnaise, mustard and catsup. Blend well. 6.
To serve, divide the catsup mixture evenly on the warmed hamburger
buns, top with a meat patty, tomato slice, onion slice and shredded
lettuce. Also good with alfalfa or radish sprouts.
