Preheat oven to 350 degrees F ( 176 C) Cut a double piece of parchment paper or aluminum foil large enough to fold over and crimp and crimp the edges.
Place a salmon fillet on top of doubled up parchment paper and top with ginger, onion, garlic, grapefruit segments, grapefruit juice, jalapeno, dried crushed coriander, salt and pepper to taste.
Wrap up salmon packets by first bring up the two edges lengthwise and fold and crimp over edges at least twice. Go to the 2 ends of the fish on parchment paper and fold over twice or crimp over the ends to prevent the juices from coming out.
Place the fish packets on a baking sheet or baking pan and depending on size of salmon fillets bake about 10 -11 minutes or until fish flakes easily with fork.
Serve fish packets to your guests right in the packet or on top of sautéed spinach for a healthy spa dinner. Garnish with cilantro stems finely chopped. Enjoy!
You can also cook your salmon packet on the grill if you place in aluminum foil.
