Also not the person you questioned, but answering about lasagne

I dont make it often becuase DH and DS will eat it but it is not their favourite, and DH has gotten to where he really wants fresh pasta for most everything (including dumpling wrappers for pot stickers). I am lazy and do not do fresh pasta dough---so mostly those recipes only get done one weekends when DH makes the dough and I do the rest (we have an attachement for pasta that goes on our mixer, he claims it is easy and he can make a batch in under 20 minutes so I guess it is).
So, for lasagne, I make vegetarian. DH starts on dough while I chop and sautee veggies. We use jarred tomatoe sauces (I have never done that homemade). By the time the fisrt noodles come out the roller I have sauce in the bottom of the pan. He drops a noodle layer on top, I add more sauce (sauce plus fresh pasta dough means no need to boil first, the juice in the sauce is enough to cook them while it bakes), ricotta/saucce/spices mix, veggies and pre shredded mozerella, by then the next noodle layer is coming out and DH adds it on (in a little square pan for one night, we don't bother to slice them into long rectangles, just put the whole square right on--fits the size of the pan perfectly.) repeat one more time and then I top it all with more sauce and spices and provolone and pop it in the oven. By the time it is done baking the prep dishes are washed, the pasta maker put away and we'ev make a salad or some broccoli to go with it.
So, it sounds like we make a much simpler version of lasagne than you do, plus we have it down to a very smooth system (and DH and I often cook together as described which makes it more fun and social and also means htings go much faster).
