Beef Vegetable Soup (Crock-Pot)

You will need:             
32 oz. organic beef broth/stock
2 small onions, chopped
3 stalks of celery, chopped
3 carrots, sliced
2 potatoes, peeled and diced
1 sweet potato, peeled and diced
1-14½ oz. can diced tomatoes with juice
½ tsp. pepper
1 tsp. salt (optional)
2 cups frozen green beans
12 oz. package frozen soup mix vegetables
1/4 cup quinoa
1 pound ground beef, browned and drained

At the end of cooking time:
¼ cup butter, melted
¼ cup flour (use brown rice flour or gluten-free flour blend if you avoid gluten)  

Directions:
Put all ingredients in the crock-pot, except the butter and flour. Cover and cook on Low for 8 to 10 hours (High for 4 to 5 hours).

One hour before serving, make a roux by melting the ¼ cup butter in a small saucepan, then stirring in the ¼ cup flour, until smooth. Add this mixture to the soup and stir. Cook the soup on High until it thickens a bit.

For variety you could:
*Substitute ground turkey or ground chicken for the beef (and use chicken broth in place of beef. I have never done this, but why not?) Or, finely diced chuck roast, browned.
*Add different vegetables

Hints:
*I usually double this recipe so I have plenty of leftovers
*Brown your ground beef (or ground turkey or chicken) ahead of time and freeze so you can put this together quickly on another day.
*No time to chop vegetables? No problem. Use a couple bags of frozen soup mix or other vegetables you like. It will be tastier than any soup that comes out of a can or box.
