Cook noodles in a very large pan of boiling, salted water until ALMOST tender (they will cook more in the oven, absorbing liquid from the sauce as they do, and if they are slightly undercooked they will hold together better while you're assembling the dish).

After draining noodles it can be helpful to submerge them in cold water.

Grease 9x13x2.5" baking dish.

Spread a think layer of sauce in the bottom, and then a layer of noodles, lengthwise (each layer of noodles should like crosswise to the one below it).

On the layer of noodles, spread the first layer of filling: 1/3 cottage cheese, 1/3 of the nuts, 1/4 Parmesan, then a coating of sauce.

Layer noodles again, then spinach and most of mozzarella, filling (as above) and sauce.

More noodles, more filling (as above), and the prettiest noodles across the top.

Top with sauce and rest of remaining Parmesan (and any other fillings that may be left).

Bake at 350 F for 30–45 minutes (if ingredients are hot, the shorter time will be enough).

Let stand 10 minutes, cut.
