Mixed Grain Mushroom Casserole

1. Combine grains in a mixing bowl and set aside.
2. Pour the oil into a 2-3 qt. casserole which is safe for both stovetop and oven cooking, and place on med. heat. When hot , saute onion and garlic until tender and translucent, about 5-6 mins.
3. Add the mixed grains and saute for 1 min. , stirring constantly.
4. Meanwhile melt butter or margarine (if using) in a separate pan on med. high heat.
5. When hot , add mushrooms and saute quickly, stirring frequently, until the shrooms are hot and have just absorbed the "butter" (about 1 min. ). Immediately remove from heat.
6. Add the broth, herbs, and mushrooms to the casserole with the onions and grains, and bring to a boil.
7. Seasoni with salt and pepper to taste, cover tightly (use aluminum foil between pot and cover if necessary for a good seal), and bake at 350 degrees F for 1 hr. NOTES: I use alot less oil (only as much as needed to keep things from sticking in my cast-iron dutch oven), add hot peppers and fresh herbs (rosemary is especially delicious; i dislike dried oregano so i use less or none), add soy sauce instead of salt, and saute the mushrooms first in the same pan (taking them out when done) so i dont have to wash two pans.
