This is something I just threw together based on similar recipes I've read on the Internet. It's really filling.
Chicken Tortilla Soup - 1 serving
Mix the following in a sauce pan and heat:
1 cooked chicken breast, cut into bite sized pieces
1 cup chicken broth
60 g (1/4 cup) salsa
28 g (1/4 cup) shredded cheese
Pour into bowl.
30 g (2 tbs) low fat sour cream
1 low carb tortilla, warmed in oven until a little crisp, cut into 8 pieces [I kept these on the side and just dipped them in the soup]
