Line inside of 4-in. (10-cm) diameter dish (about 2-in./5-cm deep) with plastic wrap. Dip pretzels in melted chocolate, stack in bottom and up sides in the bowl to form a "nest". Roll a ball of foil and place into the nest, if necessary, to create a hollow. Refrigerate 15 to 20 min. until chocolate hardens. Remove foil ball, if using. Gently loosen nest from bowl; peel off plastic wrap. Fill nest with chocolate eggs or other candy, if using. Use nest as a festive cake topper or whimsical addition to a dessert tray.
