Cook the brown rice according to package directions but eliminate the salt.
Melt the butter in a large skillet and saute the mushrooms, zucchini, onions, and garlic until tender but not browned.
Put the saute vegetables in the container of an electric blender or food processor and whirl or process until smooth. Scrape into a bowl.
Add the cooked rice, eggs, nuts, parsley, wheat germ, sage, basil, thyme and pepper. Transfer into an oiled 9x5x3 inch loaf pan and bake in a 375F oven for 30 minutes.
Cool, remove from pan, and chill. Serve in 1/4" thick slices on lettuce leaves with sour pickles.
