01 - Line a baking sheet with parchment paper. Break matzo sheets into large pieces and arrange in a single layer on the prepared sheet.
02 - Melt chocolate and butter together in a heatproof bowl set over a saucepan of simmering water, stirring constantly until smooth and fully combined. Alternatively, microwave in 20-second intervals, stirring between each burst, until completely melted.
03 - Pour melted chocolate mixture evenly over matzo pieces. Use a spatula to spread chocolate, ensuring each piece is thoroughly coated.
04 - Immediately sprinkle chopped nuts, dried fruit, and flaky sea salt over chocolate while still wet. Press toppings gently into chocolate to adhere.
05 - Refrigerate for at least 30 minutes or until chocolate is completely firm and set.
06 - Break into smaller pieces and serve immediately or store in an airtight container.
