Boil water for lasagne noodles then cook as suggested on the package

Preheat oven to 425.

Prepare the vegetables by adding the onions, carrots, and bell peppers to a pan with avocado oil. 8-10 minutes. Add some spinach, salt, pepper, seasoning, then garlic. Cook for 5 minutes until incorporated and spinach is wilted. Add in the lentils so they're incorporated

Assemble your lasagne: spread tomato sauce on the bottom of a baking dish (I used 9 x13) to form a small layer, layer lasagne noodles on top. Top with ½ of the veggies. Top with 1 cup tomato sauce. Add another layer of pasta, then the rest of veggies. Add tomato sauce then pasta noodles. Top with the final amount of tomato sauce

Wrap the dish in aluminum foil and bake covered for 25 minutes. Rotate then cook for another 5-10 minutes. It should be steaming and bubbling in the corners

Let the lasagne cool then enjoy!
