Apologies if this question posts twice - It didn't seem to go through the first time. I am looking forward to making this for my family as a pre-trick-or-treat dinner tonight. But I can't seem to figure out step 4- I need a lot more clarification on the order , particularly when to add sauce, ricotta and shredded cheese: sauce. I understand that it's 1. Sauce 2.Pasta 3. Arugala or Squash But when do you drizzle more sauce, ricotta and shredded cheese? Afterveach layer of Vegetables? I would assume so or the lasagna might be dry, but the makes it seem like you wait for a few layers of vegetables and pasta? Additionally, can you please clarify the top layer? Pasta, sauce, squash - no ricotta or shredded cheese? Thanks so much!!
