Preheat the oven to 350 F. In a medium bowl, whisk together flour, salt, and baking soda. In another large bowl, combine butter with sugar until fluffy.
Add in egg and vanilla extract, and mix until smooth. Add in the flour mixture, and mix until a thick dough forms. Fold in chocolate chips.
Roll the cookie dough into balls, and flatten slightly, place one chocolate kiss onto each cookie dough, and roll into a ball.
Place cookies at least 2-inches apart onto ungreased baking sheets. Bake for 10-12 minutes.
