I create four squares of foil that are double the size of your salmon slices.
You will then need to place the salmon in the middle of the foil packet.
Then I put the onions and peppers under the salmon.
Then apply some olive oil and salt and pepper.
I then put on a layer of pesto.
The final layer is the sliced tomatoes on the top. You then close the foil and create packets of the salmon.
You can place these on the grill. I put them in my oven at 400 degrees for 25 minutes it depends on how thick your salmon is. I check on them to make sure the salmon is pink. We like our salmon a little raw for we leave them in for less than 22 minutes.
