Preheat grill to medium-low heat.
Chop the salmon meat by using a knife or a food processor, being careful not to pulverize the meat. Mix the salmon meat with cilantro, ginger, lemongrass, garlic and salt. Form little patties directly onto the skewers using your hands. Make sure the patties are firmly attached to the skewers before putting them onto the grill.
Brush the grill with olive oil. Grill the skewers until salmon is just cooked through, about 2 to 3 minutes per side. Remove the kebabs from the grill and serve immediately with plain yogurt or favorite yogurt dip.
