Xagave and Lime Salmon

You can cook this recipe anyway you like. I found that salmon on an outdoor grill is absolutely delish!
Ingredients:
Sauce Ingredients:
Tear off eight pieces of foil; two for each piece of salmon.Place one serving of salmon on one piece of foil. Season with a little sea salt and fresh ground pepper.
Combine the Xagave, olive oil, lime juice and cinnamon in a glass measuring cup. Pour the sauce all over the salmon pieces.
Sprinkle the salmon with onions, scallions and garlic. Place the remaining pieces of foil on each serving and fold the edges to create a packet.
Bake in a preheated oven for roughly 20 minutes, till it flakes easily.
The recipe intro started out listing as a grill recipe and then it ended with an oven direction. It just doesn’t say grill temperature or what the oven temperature would be. I am guessing it’s indirect heat on the grill and or 350 degrees in the oven. Help!
I recommend putting your salmon in tin foil and placing the grill on medium heat. Grill the salmon for 8 to 10 minutes and then flip it and cook the other side for 8 to 10 minutes.
