Melt entire bag of chips and 1 Tbsp of shortening slowly in microwave or in double boiler on stove top. If using microwave, heat full power in intervals of 30 seconds at a time and then less as chips begin to melt. You want the chips and shortening to be well blended and creamy and hot. Do not overcook.

Immediately pour the can of Chow Mein noodles into the peanut butter mixture and toss lightly to coat noodles. Avoid crunching noodles. Using a spatula can help. Do this quickly, making sure the noodles are evenly coated. Drop by spoonfuls onto wax paper and gently form into the shape of a nest, leaving a hollowed area in the center in which you immediately place three M&M peanut candies to look like bird's eggs.
