This is a complete walkthrough on how to make a vegan lasagna.
Tahini sauce is used instead of any cheese or "analoge cheese substitute"
Tahini sauce is very different from Tahini, though both are often called "Tahini"
Tahini is sesame butter (ground up sesame seeds), tahini sauce is tahini mixed with lemon juice, garlic, and salt. I used about 5 or so lemons in this. Not the 3 shown in the clip. You need plenty of lemon juice or elese it stays fairly bitter.
