Recommended: Cook marinara sauce and lentils concurrently and then begin sauteing the turkey when the marinara sauce seems almost done.

Marinara Sauce (30 min, first 10 ingredients):
1. In a large pot, heat olive oil over medium heat. Add onion, carrot and garlic. Cook until soft, about 5 minutes.
2. Add whole tomatoes (with juice) and gently break apart with the spoon. Stir in remaining ingredients.
3. Simmer uncovered on low heat for 20 minutes or until sauce reaches desired consistency.

Lentils (40 min, next 5 ingredients):
1. To cook the lentils, first pick through the lentils for debris (I once bit into a tiny rock) and then rinse them in a fine-mesh colander. In a small saucepan, combine the lentils, bay leaf, garlic, salt and broth.
2. Bring the mixture to a simmer over medium-high heat, then reduce heat to maintain a gentle simmer. Simmer until the lentils are cooked through and tender, which will take somewhere between 20 to 35 minutes, depending on the age and variety of the lentils. Drain the lentils, discard the bay leaf and garlic, and set the pot aside, uncovered.
3. Stir the marinara into the lentils and warm them together over medium heat.

Turkey:
Saute in a pan with oil until just cooked, then mix with ~12 cups of the marinara sauce and let simmer for another 10-15 minutes.

Boil spaghetti until al dente. Serve.
