Place a large piece of tin foil on a work surface. Drizzle some olive oil on the bottom.
For each salmon slice, layer on the following (remember to divide all ingredients into four portions): 1/2 cup cooked couscous, one slice salmon, yellow summer squash, zucchini, tomato, onion, sun-dried tomatoes, olives, lemon slices, garlic, sprinkle with salt and pepper & parsley. Drizzle some broth and a little more oil over the top. Fold the foil edges over the salmon making a packet. Leave a little room in the packet for air to circulate.
