One way to eat it is to fix a hamburger. Here is what you do: Make hamburger patties.You do not have to fix them from scratch, you can use store bought ones and pop them in the oven or put them on the grill. While the hamburger patties are cooking take the sliced sour dough bread and spread butter or margarine on one side of each slice.Toast the bread butter side down in a skillet on medium high flame until light brown. Slice up some lettuce, tomatoes and onions. For each burger take two slices of bread ,spread some mayo on both sides and add the rest of the ingredients. If you like you can use some swiss cheese on the burgers or some sautéed mushrooms.
