Make Ahead Meals

I'm in the process of planning a giant cooking day.  I'm planning to make several meals, then freeze them.  It wouldn't really be worth it for my picky family, especially since Michael has decided he doesn't like leftovers anymore.  My casseroles consist of 2 servings - not really worth the hassle.  BUT, a friend of mine, whose family loves every food under the sun, wanted to do this, so I'll make enough for a meal for her family of 4, and save 2 little servings for us along the way.  I'll post what I end up making, but so far the list consists of soups, lasagnas, and casseroles.  I also found quick crock-pot meals.
