In a sieve, rinse lentils under running water, set aside.
Chop the onion and garlic.
Heat oil in a large pot and sauté the onion for about 3-4 minutes over medium heat. Add garlic and sauté for a further one minute.
Add all spices (Italian seasoning, onion powder, paprika, sea salt, black pepper), the lentils, tomato sauce, tomato paste, cashew butter, and the vegetable broth or water. Stir with a whisk and bring to a boil.
Meanwhile, break the lasagna noodles into smaller pieces. Once the soup boils add the lasagna noodles and cook for about 9-10 minutes or until the noodles are al dente.
Finally, add the plant-based milk (or cream), the lemon juice, and nutritional yeast. Turn off the heat.
Taste and adjust the seasonings. Add more salt, pepper, Italian herbs as needed. You can also add red pepper flakes or hot sauce for a spicier soup!
Serve immediately and garnish with fresh herbs. Enjoy!
The soup will thicken over time, as the noodles will absorb a lot of the liquid. Simply add more vegetable broth if you want to eat leftovers the next day. Store covered in the fridge for up to 5 days.
