Slice entire package of bacon down the middle. Using one of the 1/2 slices each wrap a whole water chestnut with the bacon and secure with a wooden toothpick. Bake in the oven on a foil covered cookie sheet for 25 min. While baking mix catsup and brown sugar in a bowl. After the 25 min., take out of the oven and dip each bacon wrap in the catsup mixture and replace on the cookie sheet. Bake another 20 min. Cool slightly and serve. Yummmmmmm Make enough, you will keep coming back for more!!!
