Heat oil in a large soup pan over medium-high heat. Add the chopped carrots and onion and cook until the onion starts to soften, about 5 minutes. Add the garlic and cook for 30 seconds, stirring. Add the lentils, the flavor packet, 6 cups of water, salt and pepper and bring to a boil. Reduce heat, cover the pan and let simmer for 25 minutes or until the lentils are tender. Add the salmon and simmer with the pan uncovered for 4 – 5 minutes or until the salmon chunks just start to flake and are cooked through. Stir in the Tabasco sauce and check seasoning, add more salt, pepper and Tabasco if desired.
