I had some left over roast beef and wanted
to make a nice comforting soup for lunch.
This is what I came up with, it's good!

1 onion, peeled and chopped
2 cloves garlic, peeled and crushed
2 russet potatoes, peeled and diced

2 raw carrots, peeled and sliced
1 can cut green beans
1 cup frozen whole kernel corn
2 cups beef broth
4 tablespoons flour
1 teaspoon basil
1/2 teaspoon garlic powder
1/2 teaspoon salt or to taste

Directions:
In a soup pot, place olive oil, onions, garlic.
Cook on medium for a few minutes until softened.
In a bowl toss beef with flour to coat, add to pot.
Add all other ingredients, stir to mix, simmer for an hour
or until potatoes and carrots are done.
