Preheat oven to 375. Melt the 24 oz of semisweet chips in a double boiler. Let cool. Combine the flour, soda, and salt. Cream together the butter, sugars, and vanilla. Add eggs, beat until fluffy. Blend in flour mixture. Gently toss in milk chocolate chips and M&M’s. Grab a fistful of dough and shape into a ball, and pat it down to about 1 inch thick. (These cookies are best HUGE, so only bake 2 to a sheet) Bake for about 8 minutes. They are best when slightly underdone. Let cool a few minutes before removing from sheet. Preheat oven to 375.
