01 - Heat olive oil in a large skillet over medium heat. Sauté onion and garlic until soft and fragrant, about 3 minutes. Add diced chicken, ground spices, salt, and pepper. Cook, stirring frequently, until chicken is fully cooked and liquid has evaporated, approximately 8-10 minutes.
02 - Stir in chopped parsley, cilantro, lemon juice, and harissa paste. Continue cooking for an additional 1-2 minutes. Remove from heat and let the filling cool slightly before proceeding.
03 - In a small bowl, combine toasted almonds with granulated sugar and orange blossom water. Toss gently to coat evenly.
04 - Transfer chicken filling to a large bowl and mix with the seasoned nut mixture. Taste and adjust seasoning as needed before assembling.
05 - Place one pastry sheet on a work surface and brush lightly with melted butter or oil. Place a generous tablespoon of filling near one corner. Fold the pastry into a triangle, enclosing the filling completely, similar to folding a flag. Seal the edge with butter or oil. Repeat until all ingredients are used.
06 - Heat oil in a deep pan or fryer to 350°F. Fry briouats in small batches, turning once, until golden brown and crisp, about 2-3 minutes per side. Remove with a slotted spoon and drain on paper towels.
07 - Serve hot while crispy. Accompany with lemon wedges, extra harissa, or a yogurt dip for added flavor.
