Mushroom-Walnut Loaf (Garden Loaf)

I cook the brown rice with a little toasted sesame oil to give it a nutty flavor. I love this recipe. It freezes well and easily reheats. Sometimes I add cooked sausage to the recipe, if I feel like having some meat that week. Otherwise, it's a hearty, satisfying recipe. Serve with mushroom-walnut gravy or my favorite savory sauce.
