Sprinkle salt over the mushrooms. The mushrooms will sizzle and then start to release water. (Note that you are not adding fat at this point to the pan; this method of cooking mushrooms in their own moisture is called "dry sautéing.)

Boil and drain the lasagna noodles: Once the sauce is simmering, salt the boiling pasta water, and add the dry lasagna noodles to the boiling water.  (The water should be at a vigorous, rolling boil.) Stir gently, making sure that the noodles are not sticking to each other. Set the timer for 8 minutes, or however long is indicated on the package of the noodles. Cook uncovered on a high boil.

When the noodles are ready (al dente, cooked through but still firm to the bite), drain the noodles in a colander, and rinse them to cool them with cold water.  As you rinse them, gently separate them with your fingers so they don't stick to each other.
