Lentil and Brown Rice Casserole

I had some lentils leftover from yesterday so I decided to throw it in a pan with a bunch of other stuff we had lying around, and call it a casserole. This was actually a big hit. DD ate an adult size serving, DH had two servings. Even DS had two servings, directly after which DH called out "Not it!", seeing as DS isn't potty trained yet.

You will need...
2 cups cooked brown rice
2ish cups cooked lentils
1 pkg sliced mushrooms
4 tbs butter divided
3tbs flour
2 cups milk
salt, pepper, and garlic salt to taste

In a large pot melt 1tbs of butter, add the mushrooms and some seasonings and cook until brown. Add the lentils and rice and toss to coat with the buttery mushroomy goodness. Empty this mixture into a casserole dish. Put the pot back on the stove with the remaining butter and wait until it has melted. Whisk in the flour until a paste forms and cook for about a minute more, then pour the milk in all at once and whisk like mad. Cook until thickened, season with salt, garlic salt, and pepper to taste. Pour this sauce over the top of the casserole and bake until warmed throughout.
I will admit, this is one of those dishes that made me wonder if we would have loved it as much if we ate a conventional American diet, but if nothing else it's proof that if you offer kids healthy options they will eat them...maybe not always, but sometimes. And if you just keep trying new foods different ways, you may just find yourself some day raving about lentils.....
