1To make bean mix: Measure pinto, navy, kidney, lima, and garbanzo beans, and combine in a large airtight container or bag.
2To make seasoning mix: Combine onion, paprika, salt, mustard powder, garlic, chicken bouillon powder, beef broth, parsley, bacon bits, and vegetable flakes in plastic bag and shake to mix. Place bag in bean container. Store at room temperature.
3To make one batch (6 bowls) soup, start 2 1/2 hours before. Rinse 1 1/2 cups bean mix in sieve under running water. Place beans in a three-quart saucepan. Add 5 cups water, 1 tablespoon oil, and 1/4 cup seasoning mix. (You can add 1 can tomatoes and juice at this time, or you can add the juice and reserve the tomatoes to add near the end of the simmering time.) Bring to a boil, reduce heat and cover. Simmer for 2 to 2 1/2 hours until beans are tender.
