We add lentils to this classic marinara sauce for some extra texture, flavor and protein. Enjoy it with a mixed green salad for a simple but tasty meal! If you've got time over the weekend, make the sauce ahead of time so it can develop even more flavor.
Heat a Dutch oven over medium-high heat. Add cooking oil and then garlic, onions, and green peppers to heated oil with a sprinkle of salt. Saute until softened, ~3 minutes.
Add tomato paste and ketchup and saute for another 2 minutes.
Fold in lentils, thyme, crushed tomatoes, basil, and oregano. Stir and simmer for 15 to 20 minutes.
While marinara cooks, make vinaigrette for salad by whisking together vinegar, mustard, syrup, and oil.
Toss vinaigrette with red peppers and greens.
Taste and season lentil-marinara sauce with more salt, pepper, spices, or tomato paste. Divide pasta onto plates and cover in sauce. Finish with parmesan. Enjoy with salad on the side.
