Melt chocolate chips in a microwave oven or over simmering water.
Cool to room temperature.
Combine flour, baking soda, and salt in a bowl.
Stir to blend.
In a medium-size mixing bowl, beat margarine and fructose until smooth.
Beat in vanilla and egg.
Continue beating at least 2 more minutes.
Add melted chocolate chips and beat well.
Then gradually beat in flour mixture.
Drop batter by teaspoonfuls onto an ungreased cookie sheet.
Bake at 375°F (190°C) for 8 minutes.
(Cookies will be soft.) Allow to cool on pan for 2 to 3 minutes; then move to rack.
These are crisp chocolate cookies.
If you prefer softer cookies, try putting a slice of apple in your cookie tin with the baked cookies.
