Cook ground beef with seasonings on stovetop until meat is browned (cooked). Leave meat juices in pan and add tomato sauce, crushed tomatoes, tomato paste. Stir up, then add the cheese. Simmer with lid :30 minutes.
Prepare cheese mix while meat is simmering - add all cheese mix ingredients in a bowl and stir. Then set aside.
Prepare vegetables - peel zucchini skin and then peel zucchini "noodle" slices. Cut eggplant into thin slices.
Prepare the Keto noodles (see recipe link in post above). Let cool, then slice into lasagna noodle thickness.
Layering: 1) meat sauce 2) lasagna noodles 3) cheese mix 4) vegetables 5) noodles 6) meat mix 7) cheese mix. (The layering is more of a recommendation and you can layer as you wish, however bottom layer should start with meat mix and end with cheese mix)
Top with final layer of mozzarella cheese. Bake in preheated oven 350 for 30 minutes.
