Vegetable-Almond Medley

This is kind of a throw-back, hippie kind of vegetarian dish, the kind I taught myself to cook many years ago, and I occasionally crave that kind of thing. It certainly is good for you, and you can use whatever vegetables are on hand, so it's wonderfully flexible. It takes a little while to put together, but it's worth it if you're looking for a substantial vegetarian main course casserole. It can easily be made vegan by replacing the butter for a good-flavored oil.
