  • 1/2 cup green onion, sliced
  • 2 ounces black olives, sliced

  • 1 1/2 cups cucumber, English, diced small
  • 1 1/2 cups bell peppers, red, green, yellow

  • 2 tablespoons lemon juice
  • 1/2 teaspoon garlic powder

Wash quinoa very well under faucet using a fine mesh colander. In a medium sized pot, bring water to a boil. Add quinoa. Cover and simmer approximately 15 minutes until water is absorbed. Remove from heat. Chill. Mix together dressing ingredients thoroughly. Toss over salad. Allow salad to marinate 30 minutes in refrigerator before serving. Chef’s Tip: Serve with whole grain pita bread and hummus for a great meal!

Nut Loaf

Makes 10 servings

  • 1 1/4 cups cashews, pieces, ground
  • 2 cups ground gluten
  • 1 cup onions, finely chopped
  • 1/3 cup celery, finely chopped
  • 1 cup bread crumbs, whole wheat
  • 3/4 cup soymilk
  • 2 tablespoons cornstarch
  • 1 tablespoon Bragg Liquid Aminos All-Purpose Seasoning
  • 2 tablespoons chicken-like seasoning
  • 1 tablespoon parsley flakes
  • 1 teaspoon poultry seasoning or sage

Combine all ingredients and mix well. Oil-spray 1 large or 2 small loaf pans. Pour mixture into pan(s) and spread evenly. Bake at 350 F for 45-60 minutes or until brown on top. Remove from oven and let sit 10 minutes before serving. Chef’s Tip: Loaf is more solid if prepared the day before serving. Reheat loaf and tip out onto a platter. Slice into 1/2-inch slices. Garnish with fresh parsley and cherry tomatoes. This loaf can be used on occasions in place of a turkey. Freezes well. Ideal sandwich filler, especially with pita bread.

Cranberry Orange Bread

Makes 2 loaves (16 slices per loaf)

  • 3 cups orange juice, unsweetened
  • 1 tablespoon active baking yeast
  • 1 tablespoon lemon juice
  • 1 tablespoon gluten flour
  • 1/2 teaspoon salt
  • 1 cup pecans, chopped
  • 1 cup dried cranberries
  • 3 cups whole wheat flour
  • 4 cups spelt or whole wheat pastry flour, or as needed

Warm orange juice to above room temperature, but not hot. Place in a mixing bowl. Sprinkle yeast into orange juice. Wait 10 minutes, or until yeast bubbles up to the surface. Add remaining ingredients. Add enough flour so dough is not “sticky.” Cover mixing bowl with a towel and set in a warm area. Allow dough to rise for about 1 hour or until doubled in size. Knead dough and divide in half. Form each half into a round loaf and place on a baking sheet that has been prepared using a nonstick spray. Cover loaves again with a towel and let stand for 20 minutes or until doubled in size. Bake at 350 F for 30 minutes or until golden brown on top. Cool bread on racks. NOTE: These freeze well.


His research, published in peer-reviewed journals and medical textbooks, shows that most people with essential hypertension, type 2 diabetes, elevated cholesterol, and heart disease can reverse these diseases and often become drug-free within weeks by simplifying their customary lethal American diet. In addition, overweight people learn how to eat more and lose weight on a permanent basis.

He was recently chosen by a national health magazine as one of America’s 20 superheroes in the health movement: “These scientists, through research, education, advocacy and public relations, have brought intelligent, well-reasoned new voices into the discussion of health care.”
