Step 1
In a large saucepan, heat oil over medium heat. Add onions, mushrooms, zucchini, and garlic. Cook and stir until tender, about 5 minutes.
Step 2
Add lentils and 3 cups water to vegetables. Bring to a rolling boil, stirring occasionally. Reduce heat to low, cover, and cook 45 to 60 minutes.
Step 3
Stir in tomato sauce, tomato paste, sugar, and 1/2 cup water. Bring to a boil. Reduce heat, cover, and simmer for 20 minutes. If necessary, add more water to keep the sauce from sticking. Be careful not to dilute; the sauce should be quite thick.
