Tuna Bean Soup

• 1 large onion, chopped
• 1/4 lb fresh sliced mushrooms (I add more)
• 5 cups chicken broth, divided
• 2 (15 ounce) cans pinto beans, rinsed and drained (30 ounces total)
• 2 (15 ounce) cans kidney beans, rinsed and drained (30 ounces total)
• 1 (28 ounce) can chopped tomatoes, undrained
• 1 (8 ounce) can tomato sauce
• 1/2 teaspoon oregano leaves
• 1 (7 ounce) can canned tuna, drained & flaked (14 ounces total)
• 4 sliced green onions
• red pepper flakes (optional)
• sugar (optional)

1. Saute the onions and mushrooms 8 minutes. Add 1/4 cup broth to deglaze the browned pieces.
2. Add the remaining broth, beans, chopped tomatoes, tomato sauce, and oregano leaves. Bring to a boil, reduce heat and simmer, covered, 15 minutes or longer, if you prefer.
3. Stir in the tuna last. If you wish, add red pepper flakes and sugar according to your taste. Top bowls of soup with green onions.
