1. Saute your onions and garlic in the butter until translucent, about 5 or so minutes. 2. I start with 2 cups water and simmer your carrots in the same pot as the onions and garlic until just about tender. About 20 minutes or so. 3. Add your lentils and make sure you've got enough water to cook them without sticking to the bottom! 4. Let the lentils simmer about 15 or 20 minutes or until tender. 5. Season with your curry and salt and pepper to taste.
