Unlike some lasagnas this one comes together quickly. You don't want to cook the sauce too long because you want to emphasize their freshness. Serve this with a big green salad and you have a filling, but not heavy, meal.
I do not find it necessary to cook dried lasagna noodles before assembling the casserole. They always cook just fine on their own, when layered between all the goodness inside. My sister-in-law let me in on that little secret years ago, and it hasn't failed me once.
