Melt 8 ounces chopped semisweet chocolate in a heatproof bowl set over a saucepan of simmering water, stirring. Remove the bowl from the pan and stir in 2 cups canned potato sticks. Coat a 6-cup muffin pan with cooking spray and scoop some of the chocolate mixture into the cups; make an indentation in each to form nests. Chill until set, at least 3 hours. Fill with marcona almonds.
