Veggies: Mince the onion. Peel the carrots. Cut the carrots and zucchini into small dice. Alternatively, chop everything with a food chopper.
Sauté the veggies: Add the veggies to a large skillet with olive oil. Sautö for 10 minutes over medium-high heat until soft and golden.
Cook the "lasagna": Add the drained and rinsed lentils, passata, vegetable broth, and Italian spices to the skillet. Give it a good stir. Break your lasagna noodles into large pieces (I aim for 4 per sheet). Nestle them into the sauce horizontally so they’re mostly covered but not overlapping. Bring the sauce to a simmer, then cover with a lid and let it cook for 20-25 minutes, or until the noodles are tender.
Make it creamy: Stir in the cashew butter and nutritional yeast. Let it bubble for 1-2 more minutes. Adjust seasoning with salt and pepper if needed. That's it!
