2 1/2 cups almonds, toasted and coarsely chopped, divided
1 cup (2 sticks) margarine or butter
1-1/2 cups packed brown sugar
1-3/4 cups (from 11.55-ounce package) chocolate morsels or chocolate chips
Place nuts on a baking sheet lined with parchment paper or well-greased.
Melt the margarine in a medium, heavy-duty saucepan over medium heat. Stir in the sugar. Bring to a boil, stirring constantly, until the mixture reaches 280 degrees F on a candy thermometer, about 7 minutes.
Pour the hot mixture over the nuts; let stand for 5 minutes. Sprinkle with morsels. Let stand until morsels melt and become shiny and soft, about 5 minutes. Spread evenly.
Refrigerate for about 20 minutes. Break into bite-size pieces.
