In a medium bowl, cream together the butter and sugar substitute. Mix in water, vanilla, and egg. Sift together the flour, baking soda, and salt; stir into the creamed mixture. Mix in the chocolate chips and pecans. Drop cookies by heaping teaspoonfuls onto a cookie sheet.
Bake in the preheated oven for 10 to 12 minutes. Remove from cookie sheets to cool on wire racks. These cookies freeze well.
