Preheat oven to 250. Lay herbs on a sheet pan and then place salmon on top of then. Coat in olive oil, salt and pepper. Bake for about 45 min or until salmon is just a little pink inside.
Meanwhile in a food processor or blender, combine all spread ingredients. Blend until smooth. Season to taste.
Coat bread in olive oil and cook in a skillet for 2-3 min per side. Slice cucumbers and tomatoes. Add spread to bread and then add spinach, cucumbers and tomatoes. Top with flaky salmon and enjoy!
