Line a separate large baking sheet with nonstick foil. Melt chocolate in a heatproof bowl set over a saucepan of simmering water. Stir chocolate until smooth, about 4 minutes. Remove bowl from heat and stir in half each of berries and nuts.3. Immediately pour chocolate mixture onto foil; spread evenly into a 16-by-11-inch rectangle. Sprinkle with remaining berries and nuts, pressing gently into chocolate. Chill for 30 to 40 minutes or until very firm. Break into about 34 3- to 4-inch pieces. Store between pieces of parchment in an airtight container in a cool place.
