Based on Jeff's SNAP meal ideas
3 or 4 large sweet potatoes peeled and chunked( not pre cooked)
2 cans black beans..15 oz size
2 cans diced tomatoes..15 oz size
10oz package of frozen spinach
1 large onion diced
put everything in a soup pot..add water or broth to cover all.(sorry I don't measure and I used water)..add spices..I used garlic and onion powders, salt and pepper(again I don't measure add to your taste)....bring to a boil then reduce and simmer until the potatoes fall apart...at this point I used a potato masher to finish mashing the potatoes., by doing this it made a nice thick soup....very yummy
