I would have to say my first round of Manicotti was very successful! Although, I think for my second round I am going to make some adjustments. I made the meal for my boyfriend and myself and we both enjoy cooking when we have a chance and this made for some interesting dinner conversation.
We both found the ricotta made the dish very heavy and thought cottage cheese would be a good exchange for the next time. I am also going to replace fresh chopped spinach for the frozen for a fresher taste in the filling and completely omit the nutmeg! This gave an undesired taste, at least for me.
As for the marinara sauce, It was good, but I found it a bit loose. I prefer my sauces a little thicker, so I think it needs some tomato paste and for some depth a little red wine will perk it up. I did not care for the thyme in it either so I plan on replacing that with oregano, and I will use dried herbs instead of fresh, as I have them in my cupboard and fresh are very expensive. (I love fresh herbs, but I have good luck reviving dried herbs by rubbing or steeping  for recipes.)

By the way I served the manicotti with a homemade rosemary focaccia and a romaine, radicchio salad with a simple herb vinaigrette.
