This was ok. I doubled the recipe and because I didn't have oregano, I used cilantro. I also used sour cream instead of yogurt. It had a nice flavor but the tortillas became quite soggy and didn't hold together at all. The serving ended up being a wad of lasagna on the plate. I have no idea how the picture looks so nice with the tortillas clearly in one piece. Maybe, like the other commenter, I should have toasted them first. If I make this again, I will probably just bake the mixture, top it with sour cream and shredded lettuce, and eat it with tortilla chips.
