Combine the ingredients: garlic, maple, soy, oil, salt, and pepper in a small container.

Put a salmon portion on each square of foil. Spoon some sauce over the fish.

Add a lemon slice on top and seal the foil packet.

While at camp, heat a skillet on a single burner over a medium-low flame.

Cook packets for 10 to 12 minutes, flipping them once, until the salmon flakes.

Open foil carefully, and away from your face. And serve.
