01 - Cut salmon into chunks and pulse in a food processor until coarse mixture forms, avoiding overprocessing into paste.
02 - Transfer salmon to a bowl. Add harissa paste, garlic, scallions, cilantro, cumin, panko breadcrumbs, sesame seeds, salt, pepper, and egg. Mix until just combined.
03 - With damp hands, shape mixture into 8 small patties. Sprinkle extra sesame seeds on top, pressing gently to adhere.
04 - Heat olive oil in large nonstick skillet over medium-high heat. Fry patties 3-4 minutes per side until golden brown and cooked through.
05 - Serve hot, garnished with additional cilantro or lemon wedges if desired.
