1. Fill a small pot with water. Add a dash of salt and lentils. (The lentils can be pulverized slightly in blender beforehand, if you like, meaning the lentils will cook faster.) Bring to boil over medium-high head (second-highest setting), uncovered, stirring every few minutes, until lentils are tender (but not too mushy, if you didn't pulverize them).
2. While those cook, heat olive oil in a skillet over medium-high heat. Fry your onion until softened slightly. Add garlic and sauté for a minute or two more. Add tomato sauce and tomatoes. Turn down heat slightly. Add a splash more oil.
3. When lentils are tender, drain and add to the sauce. If the sauce seems to be drowning the lentils, cook for a little longer. If the lentils seem too thick, add some more tomato sauce.
4. Add herbs, black pepper, sugar, and tumeric. Serve over pasta (cooked via the package's instructions).
